Abelia aff. floribunda
This more than lovely plant, collected in the late 1980s by Dennis Breedlove in the southern Mexican highlands, can behave as loose groundcover or as a vine with soft-textured, apple-green leaves that go deciduous only with extreme drought. Flowers of over 2" are light pink flowers and rather open with an intoxicating perfume. Enjoys frequent summer moisture and dappled shade in all but coastal areas. A very good container plant. Has frozen to the ground and recovered twice in our Portland garden at temperatures around 20F, so we say, frost hardy in USDA zone 9a and above.

Polycarpic and rare in cultivation, these plants, found clinging to the high rocky mountains between Saltillo and Monterey in NE Mexico growing with pines and, yes, even Douglas fir, love the cool summer nights of the Northwest. Slow growing, each rosette to 1 ft tall x 18" wide, gradually forming a wider clump. Sun to part shade in well drained soil with occasional summer water. Frost hardy to 10F, USDA zone 8, when kept dry in winter.

Agave bracteosa 'Monterrey Frost' Monterrey Frost Century Plant
Rare form of A. bracteosa, only recently available to the public, but high on the agave lovers "want" list for some time. Plants eventually reach 1 ft tall x 1.5 ft wide with leaves that can either be described as green with wide white margins or white with a green stripe down the middle -- both are true. Offsets occasionally in maturity. Prefers lean soil that drains well and protection from the hottest sun, so light dappled shade or afternoon shade. Frost hardy in USDA zone 8. Lovely in a container.
Agavaceae $24

Agave dasylirioides
New and obscure little century plants from Oaxaca, Mexico appear almost like sea urchins perched on their jagged limestone habitat. Each plant to about 6” or so with narrow, quill-like leaves of dusty blue green. Flower spikes, reaching to 8 ft or higher on mature plants, signal the end of the rosette. Sun to part shade in well-drained soil with only occasional summer water. Frost hardy only into the low 20sF, USDA zone 9, but a beautiful and manageable pot specimen.
Agavaceae $15

Agave difformis
This is a more upright form of A. lophantha from a bit further south in Mexico forming clumps, each rosette to about 10” and very symmetrical with leaves blue-green above -- often centered in a creamy green -- and lighter beneath. We were suspicious at first of this plant’s frost hardiness but it has performed well in our garden and we have rosy reports from the USDA zone 7 garden of Tony Avent in North Carolina. Provide more protection under 15F where winters are wet. Very good container plant.
Agavaceae $16

Agave funkiana 'Fatal Attraction'
Another selection of the already handsome A. funkiana, this with darker green leaves and and pale green midstripe down the center. Leaves are narrow and toothed, ending in a dark and pointed spine tip. For sun and well-drained soil, as expected. Drought tolerant but occasional summer water speeds growth. Less frost hardy than the species, to 15F, mid USDA zone 8. Does well in containers.
Agavaceae $16

Agave geminifloratwin-flowered agave
A rare relative in the Agave filifera group, this southwestern Mexico native has intriguing deep green rosettes of rubbery, somewhat weeping leaves with enchanting silver-white filifers toward the center of the rosette. Can even produce a short trunk. A tender species damaged under about 20F, USDA zone 9, it is best in a tall pot where its weeping foliage can spread out and over the rim. When the plants reach 1 ft. or more in diameter, they produce a spike of flowers well over 5 ft tall at which time, hopefully, they will produce an offset or two.
Agavaceae $15

Agave gentryi 'Jaws'
From an intriguing group in an even more intriguing part of the world, northeastern Mexico's Sierra La Peña, a floristically rich part of the world. Three agaves inhabit the upper slopes from 8-9,000 ft, this one now being settled on the species A. gentryi. Beautiful gray-green rosettes of sharply pointed leaves with jagged serrations and embossed impressions of the older leaves on each emerging new. This selection was made by the Yucca Do boys in the early 1990s and has been very slow to offset. To about 24-36" or more eventually, this selection, found amid pines and oaks in light shade on rubbly limestone outcrops, has taken a myriad of garden conditions. Quite happy in dappled shade but beware of wet leaves sitting in the crown in winter. It is exquisitely beautiful for the deeply indented leaf margins and double, reddish teeth. So far, unharmed in upper USDA zone 7 winters.
Agavaceae $18

Agave gentryi [La Encantada]
Recently introduced, this high mountain century plant, rather large-growing, to 5 ft or more, has bold, deep gray-green leaves forming large single rosettes before pupping. Eventually produces a red-stemmed flower stalk approaching 20 ft tall!. Perfect windowsill plant – NOT! This form appears to have had some dealings with nearby A. scabra as it has a bluish cast to the leaves not often found in the species. Quite capable of enduring garden water and partial shade. Frost hardy at 10 to 15F, bottom of USDA zone 8. Otherwise a wonderful large container specimen.
Agavaceae $16

Agave gentryi x montana
Collected originally in the Sierra Madre Orientale of northeast Mexico in an area where the majestic A. gentryi meets the more refined and smaller A. montana. The most beautiful silver-gray color represented here suggests that A. scabra, the universal partygoer of that region, has come along for the ride as well. To 4 ft wide, this stunning plant is tolerant of garden moisture --provided drainage is good -- and prefers full sun for best color. Cold hardy to 10F, USDA zone 8. Fast growing.
Agavaceae $17

Agave gracilipes - red spined clone slim footed agave
A red-spined selection of this hardy and diverse species, a natural hybrid of A. neomexicana and A. lecheguilla from West Texas, New Mexico and Chihuahua, Mexico. These have narrow green to gray-green leaves with curved spines along the sides and a sturdy, sharp tip, very red in this form. Rosettes reach 12-18” tall x 18” wide and remain solitary, rarely offsetting. Best in lean, well-drained soil with occasional summer water for best growth and appearance. Frost hardy to at least –20F, USDA zone 6 and possibly lower.
Agavaceae $16

Agave havardianaHavard agave
One of the best and hardiest agaves, with olive-green, often dusty-blue curving leaves in the classic agave shape. Big, robust, and wickedly spined. Usually a solitary rosette, though sometimes with pups. To 2 ft tall and wide. Best with good drainage and full sun. Frost hardy to -10F, USDA zone 6, or lower. Found in Texas, New Mexico, and Coahuila, Mexico.
Agavaceae $16

Agave lophantha 'Quadricolor' Quadricolor Centuy Plant
This lovely Japanese selection of an easy to grow species is small, only to about 6-8", with shiny green leaves edged cream and tan. Eventually forms clumps of several rosettes. A superb container specimen or rock garden creature where temperatures seldom fall to 15 F, mid USDA zone 7. Best if kept out of hottest afternoon sun in well-drained soil with occasional summer water where dry.
Agavaceae $19

Agave macroculmis YD 129
From several places in northeastern Mexico, this collection, from mountain ranges north of Potosi at nearly 7000 ft in oak, pine, and yes...douglas fir, forms colonies of 4 ft rosettes tinted a lovely blue-gray and showing the leaf scars to beautiful effect as each new leaf emerges. The leaf margins are undulating and decorated with dark spines. So far these have proven frost hardy to the low teens F, low to mid USDA zone 8, and are quite happy with abundant garden moisture so good drainage and air circulation in the winter is helpful. Fine pot specimen.
Agavaceae $15

Agave montana ‘Baccarat’
A selection by Yucca Do Nursery, from high elevation in Mexico’s Nuevo León Province, named after a fine crystal because of the leaf imprints on the backs of glaucous leaves that end in spiny black tips - very dramatic. Forms striking clumps to 2 ft tall x 3 ft wide. Sun, lean soil, and good drainage. Frost hardy in upper USDA zone 7.
Agavaceae $15

Agave murpheyimurphey's agave
Sweet little agave, from mid elevation deserts of central Arizona into Sonora, often found associated with Native American sites. To 18", or 2 feet at most, with narrow, upright leaves, slightly recurved and steel to powder blue. Offsetting fairly quickly. The eventual flowers also produce tiny bulbils -- as the song goes -- which might explain its being spread by people in the early days. Because of its drier habitats we keep ours in pots with very well drained soil, or only in the most exposed areas of our garden and growing in true grit. Full sun. Again, dry conditions with an occasional splash of summer water. Cold hardy into upper USDA zone 7 if dry.
Agavaceae $16

Agave murpheyi ‘Variegata’
Another sweet little agave, from mid elevation deserts of central Arizona into Sonora, Mexico. Up to 18" to 2 ft tall with narrow, upright leaves, wavy with creamy yellow margins, the centers steel to powder blue. Offsets quickly. Best planted in truly gritty soil in pots or exposed garden areas with full sun. Provide good drainage and dry conditions with a bit of summer water. Frost hardy in upper USDA zone 7 if dry in winter.
Agavaceae $17

Agave neomexicana Trailer Park Mescal
A tough-as-nails species, closely related to A. parryi but with narrower, deep blue leaves held upright and out and adorned with gray marginal spines and long, terminal brownish red spines. Slow growing to an eventual 1-2 ft tall x 2-3 ft wide, offsetting to form colonies. After 15 years or so, produces yellow flowers on a 12 ft stalk! Full sun and lean, well-drained soil with little, if any, summer water. This native of southeastern New Mexico is one of the hardiest species; to -20ºF, USDA zone 5, with good drainage.
Agavaceae $14

Agave ocahui Nerf® spined agave
This symmetrical and architectural century plant from Sonora -- to under 18" to 2 ft with shiny forest-green leaves and cream to mahogany edges -- is underutilized in both garden and container. The flowers stems are quite narrow, to 12 ft or more in height after several years, but it is really the unusual rosette we are after. Our favorite specimen is in a deep brown Chinese urn that reflects the color of the leaf margins. Low to medium nutrients maintain compact growth. This collection, by Greg Starr from one of its northern sites a few miles south of the Arizona border, has been frost hardy to nearly 10F with good drainage. Protect in containers below upper USDA zone 8.
Agavaceae $18

Agave ornithobroma
Wonderful, short-trunk forming species from subtropical western Mexico, these collections from Sinaloa at under 500 ft elevation -- did we say warm? Closely related to A. geminiflora, the 18" rosettes, with extremely narrow, flexible leaves of dark green, are beautifully framed by a gazillion curly white filifers or hairs. Quite happy with a fair amount of moisture; winter drought decreases chance of problems. We have had this in our garden, hardy for the last few years with luck. Really, it should be protected below the mid 20ºs F so best for mildest parts of the world or as fabulously small-scale container plants. USDA zone 9/10. Full sun to dappled shade in a bright window, or your nearest lava outcrop.
Agavaceae $16

Agave ovatifolia 'Frosty Blue'
A Cistus introduction and new. This mega-century plant, first discovered by Lynn Lowrey in northeastern Mexico some 30 years ago and just named recently by agaveist Greg Starr, might be the largest of the cold hardy agaves, reaching eventually to 6-8 ft with beautifully formed, blue leaves. Our selection, made from a more recent batch, has a distinct, pale aquamarine hue with the classic shape of cupped, upright, and slightly outward bending leaves. The species has taken the cold and wet of Dallas TX, for instance, so upper USDA zone 7 for cold hardiness; possibly colder in gritty or dry soil. Fabo container plant.
Agavaceae $22

Agave ovatifolia [Sierra de Lampazos clone] whale's tongue agave
One of the most beautiful century plants, found in the Sierra de Lampazos in the early 80s by the late great plantsman, Lynn Lowrey and only named in 2004 by agave-ist Greg Starr. Growing in a limited range of pinion/juniper/oak country above 8000 ft, the chalky blue rosettes, exceedingly wide and beautifully toothed, can reach over 5 ft in width giving the appearance of a much more tropical species. Has proven to be one of the best performers where cold and wet is experienced in winter and has, thus far, proven hardy to 0F, USDA zone 7, or even a bit lower. Sun to dappled shade; drainage is always a plus.
Agavaceae $17

Agave parryi (aff. var. couesii) SBHMPS 6725
From one of our favorite places in Arizona, east of Prescott amid nolinas and ponderosa pines, this extremely hardy century plant grows in colonies of giant (nearly 2 ft), blue, artichoke-like rosettes. Its habitat is a cold climate where temperatures frequently drop below 0F and the ground is snow covered or frozen for long periods of time.These plants should be hardy to well below -10F, USDA zone 6. Although this population exhibits characteristics of both A. parryi and A. couesii, what we know for certain is that these beautiful blue plants are from the highest elevation we have ever found the species and should be exceedingly frost hardy with good air circulation, bright light and good drainage.
Agavaceae $16

Agave parryi (aff. var. couesii) SBHMPS 6728
From the high ponderosa woods at over 8,000 ft between Jerome and Prescott, Arizona, where, in 1981, we first set our eyes upon this particular "patch" growing in light shade with beautiful, 24", blue "artichokes" and dozens of offsets spreading from the plants, seemingly in a race to get to a nearby clearing. Sometimes the reason the plants are brought into cultivation is simply because they are easy to propagate. This little agave is both beautiful and.... we can make more. The same culture as for other Agave parryi with dappled shade to bright light and fairly free drainage. This clone, however, should be exceedingly frost hardy to at least -10F, USDA zone 6, possibly colder. Should still be provided winter protection if grown in container below USDA zone 8.
Agavaceae $17

Agave parryi [N. of Sedona, AZ]
Tightly clumping agave with seriously impressive leaves and extremely sharp spines. A Cistus collection found north of Sedona Arizona, this form reaches 3 ft tall and wide. Best in full sun with excellent drainage and occasional water in summer for best appearance. Cold hardy to 0F, USDA zone 7 if kept dry in winter.
Agavaceae $16

Agave parryi var. huachucensis 'Huachuca Blue'
A Cistus introduction, bluer than its near relation. Our fabulous selection -- from 7000 ft in the Huachuca Mountains in southern Arizona and into northern Sonora -- exhibits particularly steel-blue leaves in the classic 20-24” artichoke shape, eventually offsetting and forming small colonies. Though not the most frost hardy of the A. parryi clan, still takes 10F in stride, USDA zone 8, and lower if very soil is well drained. Full sun in lean, well-drained soil with occasional summer water in dry climates.
Agavaceae $16

Agave parryi var. parryicentury plant
Strikingly handsome agave with blue-gray, sharp-spined leaves that show the imprint of newer leaves. To 2 ft tall at maturity, these are best in full sun and soil that is lean and very well-drained. Extra protection from winter moisture increases frost hardiness. Frost hardy in USDA zone 8 with that excellent drainage. Good in containers as well, with extra protection in winter cold.
Agavaceae $16

Agave parviflora [Ruby, AZ]
A jewel-like miniature agave from the dry grasslands of southern Arizona and adjacent Sonora, a habitat that includes Dasylirion wheeleri and the famed Opuntia violacea v. santa rita, and a rich area where we have selected forms of heucheras, Zauschneria arizonica, and numerous desert ferns. Rosettes of only 6- 8", with narrow leaves, deep green marked white, and curled filifers that make it an intriguing plant for container or garden. The flowering stalks are tall and narrow; the unusual, creamy flowers tinted red, make hummingbirds very happy. Provide excellent drainage in bright light to only the lightest of shade for best form. The habitat has dry winters and thunderstorm laden summers so these plants are best well watered in summer and kept dry in winter, though plants in our Portland garden have been quite happy for some years in a stone wall with no cover. Frost hardy from 0 to 10F, USDA zone 7; colder if kept winter dry.
Agavaceae $16

Agave parviflora ssp. flexiflora
Another rare plant from southeastern Arizona and further south with small jewel-like rosettes of under 6" consisting deep olive-green leaves marked white with occasional filifers and eventually producing narrow spikes of red-tinged flowers. Occasionally offsetting -- rather than off-putting. For sun and well-drained soil. Accepts average moisture if the soil is well-drained. Frost hardy at 12 to 15F, mid USDA zone 8.
Agavaceae $16

Agave schidigera 'Black Widow'
A compact selection of this native of western Mexico. The dark green leaves are rigid, widest in the center and narrowing to a sharp spine, with silvery markings and showy filifers along the edges. Plants can reach 1 ft tall x 18” wide forming dense symmetrical rosettes that rarely offset. Lean soil and full sun are fine in coastal climates; protection from hottest afternoon sun is important inland. Prefers regular summer water. Frost hardy in USDA zone 8. Also makes a charming container plant.
Agavaceae $16

Agave schidigera 'Shira ito no Ohi' Queen of White Thread Century Plant
The cultivar name (NOT translated as "Honey, I shrunk the kids") refers to the silky threads or filifers that decorate these rosette-forming agaves. They are solitary plants, to 18" tall and wide, with the dark green leaves, strikingly variegated with creamy margins, the quite symmetric filifers adding to the show. The species, from the high country of Mexico's Durango State, shows a decent tolerance for moisture and frost in USDA zone 8. But temperatures below 20F, bottom of USDA zone 9, can mark the beautiful variegations so we recommend a moveable container.
Agavaceae $16

Agave stricta - dwarf blue form
From central northern Mexico at mid elevations and appearing as little, blue-green sea urchins, to on 6-10". A fine addition to a detailed area of the garden where moisture can be controlled and temperatures are not likely to drop below 18 to 20F, upper USDA zone 8, for any length of time. Otherwise a striking, small container plant for bright light.
Agavaceae $18

Agave toumeyana var. bella Toumey's century plant
A rare and unusual plant with particularly dense rosettes, to 1 ft x 1 ft. The narrow, dark green leaves have striking white markings with decorative filifers or threads an added attraction. A colonizer from high elevations of central Arizona, this form makes a fine rock garden specimen if excellent drainage and bright light can be maintained. Protect from excess winter moisture. Cold hardy to -10ºF, USDA zone 6, or below in dry soil.
Agavaceae $16

Agave utahensis ssp. kaibabensis SBHMPS 6747
From the Tuweep area on cliffs and mountaintops on the northern edge of the Grand Canyon abyss amid junipers and beautiful red rocks ... and far away from restaurants that serve alcohol, our collection of a particularly wide and long leaf form of the highly variable Utah agaves, producing nearly 18” rosettes of a cheery blue-green with dark, evenly set spines. I believe this colony to be under the form kaibabensis. These plants offset rather sparsely to make attractive clumps rather than colonies. After 10 years or so, flowers spikes rise to nearly 10 ft. Though one of the most frost hardy agaves, they do like their drainage, so in areas of high moisture, best placed in stone walls or under cover. Cold hardy to about -20F, USDA zone 5. Good container plant anywhere.
Agavaceae $16

Agave utahensis v. eborispina
Exquisite form, the most northern agave anywhere!, with 6-10" rosettes of chalky blue leaves and ivory, corkscrew spines, sometimes black-tipped, up to 1.5" long. Ooooh! Offsets to form small clumps. Bright sun with very good drainage. Perfect for your limestone crevice. Frost hardy to well below 0F, USDA zone 7. (Did we mention really really good drainage?)
Agavaceae $16

Agave victoriae-reginae 'Porcupine'
This selection from Yucca Do Nursery has indeed white-tipped, porcupine quill-like leaves with gentle patterning on a symmetric plant (think of the shape of artichokes), making it a more dazzling creature than the typical Agave victoriae-reginae. Slow growing but worth the wait. Bright light, good drainage, and, preferably, protection from winter wet. Frost hardy to below 10 to 15F, USDA zone 8, depending on moisture.
Agavaceae $15

Agave victoriae-reginae var. compacta Queen Victoria Agave
A beautiful compact form of an ever-popular species. Each olive green rosette consists blunt, black-spined leaves marked with wide, silvery white striations. Each rosette grows to about 6" or less in width, clumping after a year or two. Bright light and good drainage. One of the hardier species, originally from near Saltillo in northern Mexico, it has been rated frost hardy to 10F, USDA zone 8, but has survived in dry winter places such as Denver to well below 0F, zone 7. If this makes you nervous, it makes a beautiful potted specimen.
Agavaceae $15

Agave weberi 'Arizona Star'
A most fortunate find at Mountain States Nursery of this round, blue-green century plant, to 2 ft, with leaves that are soft for the genus and, in this clone, streaked and edged creamy yellow. Very easy with bright light, good drainage, and occasional summer water. Best kept dry in winter. Vigorous and frost hardy to 15F or so, mid USDA zone 8. Otherwise, a fabulous container plant.
Agavaceae $18

Agave x arizonica - cl 2
Wonderful endemic from central Arizona, almost undoubtedly a natural hybrid, originally from only a few plants growing among chaparral in miniature oaks and manzanita. This selection, given to us by the late agave God, Howard Scott Gentry, is of great ornamental and sentimental value to us. Rosettes are fairly slow growing, to 12" or so, with glossy green leaves edged in mahogany, slowly forming a colony to 2 ft across. Beautiful for rock garden, dry stone wall, or container. Not particularly fussy about moisture, though careful drainage and bright light are always a plus, and drier winter conditions can add several degrees. In our high desert, eastern Oregon garden survived a dip to -12ºF, upper zone 5, in 1990 under bone-dry conditions.
Agavaceae $22

Agave x ferdinandi-regis
This little century plant comes from one of the more exciting habitats in agaveland, a series of mountains northeast of Saltillo in northwestern Mexico where the beautiful A. victoriae-reginae crosses with both A. scabra and A. lechugilla. The form of this plant is particularly upright, its leaves marked white with a pinkish gray cast and topped with black spines. Reaching 12-18" and offsetting freely, it is hardy to between 0 and 10F, USDA zone 7, with excellent drainage. Full sun. Excellent pot specimen.
Agavaceae $16

Agave x ferdinandi-regis 'Saltillo Splendor'
A Cistus introduction. From the famed hills west of Saltillo, Mexico where several species of century plant integrate creating, most beautiful hybrids, our collection from December 8, 1993 as a single pup that has slowly increased over the years. Very symmetric, gray-green leaves having the texture of suede with bold white streaking and three prominent black tips. Has been frost hardy to at least 12F, lower USDA zone 8, if winter dry; otherwise very good rock garden/wall or container plant,
Agavaceae $24

Agave x gentryi
Shared with us by Yucca Do and Plant Delights nurseries, this recently named species is very possibly a natural hybrid. This high elevation collection from southeastern Nuevo León at 9,500 ft might well represent this plant in its purest form. Growing to nearly 3 ft tall and even wider, the glossy green leaves, with upturned tips and very dark spines, make it a very striking garden or container plant. We estimate hardiness as low as 0 to 10F, USDA zone 7, with good drainage.
Agavaceae $16

Agave x gracilis
The name A. gracilis applies to a group of plants in northwestern Texas into New Mexico, natural hybrids between A. lecheguilla and A. neomexicana. This forms blue-gray rosettes of narrow leaves with horizontal striping. Rosettes of about 12” make a dense colony if allowed. Bright light and average to gritty, well-drained soil. Collected in the Guadeloupe Mountains in southeastern New Mexico at 6200 ft making frost hardiness probable well into USDA zone 6.
Agavaceae $15

Agave x leopoldii
Compact and most architectural century plant brought to us by Yucca Do Nursery with narrow, slightly curved leaves, a gray-blue-going-green sheen complete with a few stripes and polka dots. Offsets eventually. A most attractive, small container plant, rarely growing more than 18”, and a great addition to the dry or rock garden in a sunny site with gritty soil. Frost hardy in USDA zone 8, to 15F or so and as low as 10F if protected from overhead moisture.
Agavaceae $16

Akebia longeracemosa 'Victor's Secret' Chocolate vine
Most unusual for the genus with attractive evergreen leaves, almost butterfly-like, and racemes, to 5" or more, of vibrant pink flowers lasting a long season. Otherwise the same fascinating (intimidating?) fruit aging to a nearly metallic blue. All this on a vine of about 10 ft; not as vigorous as some others. Full sun for best flowering though perfectly at home in shade. Frost hardy in USDA zone 7, to just above 0F.
Lardizabalaceae $15

Aloe ‘Brass Hat’
A most wonderful Hummel hybrid with dark bronzy leaves and rosettes forming clumps of 6” to 1 ft adorned throughout the year with brassy orange flowers. The cross, as follows -- A. (A. haworthioides x A. bakeri) x ((A. descoingsii x A. calcairophylla) x A. bakeri) -- seems algebraic and daunting. The plants are not. Alas, frost hardy only to about 25F, mid USDA zone 9, so take precautions. Great container plant. Keep dry in winter.
Liliaceae $12

Aloe striatula
Multi-trunked shrub from South Africa, the hardiest of the shrubby aloes. To over 3 ft tall and possibly up to 6 ft wide with dark green leaves, long, narrow, and pointed, and yellow flowers in spring and summer continuing into fall. Plant in sun where drainage is good. Top hardy to 18 F, upper USDA zone 8; has resprouted from 0F, zone 7, or below with mulch, good drainage, and protection from winter moisture.
Liliaceae $12

Aloe variegata
Unique small species from the high elevations of the South African Karoo, this collection from the Sutherland Plateau. Scarce in habitat, the partridge-striped, compact leaves, marbled and striking green and white, form small clumps under shrubs or in pots in captivity, producing up to 2 ft spikes of very large orange flowers in late summer. From higher elevations, this is one of the frost hardier aloes from an area that receives winter and summer rainfall, though not a whole bunch of it. In cultivation, certainly prefers gritty soil. Best in full sun, though dappled shade isn't a problem especially in hot climates. It has been tolerant of lower temperatures, to around 10 to 12F, bottom of USDA zone 8, briefly, possibly even colder if dry. Once a common grocery store plant, now difficult to find.
Liliaceae $11

Alstroemeria psittacina ‘Variegata’ White Edged Princess Lily
A plant with many common names including Peruvian parrot lily, for it's red flowers tipped in green and white, and lily-of-the-Incas, referring to its origins in South America. This Japanese selection has variegated foliage, grayish green with irregular white edges, on stems to 12-18" tall that form slowly widening clumps (eventually enough to share...). Stems emerge in early autumn, flowering in spring and enjoying a period of dormancy in summer. Best in sun to part shade with regular summer water. Frost hardy to at least the bottom of USDA zone 7 with mulch.
Amaryllidaceae $9

Amaryllis belladonna Naked Lady
A choice and deliciously fragrant flowering bulb to perfume the late summer garden with abundant light to dark pink trumpets on dark stems, to 18-24” -- “naked” since the strappy leaves that appeared in winter have died back during the summer. Definitely a beautiful lady. Best in a Mediterranean climate with summer heat, good drainage and very little summer water. Hardy in USDA zone 8 and in zone 7 with a bit of mulch.
Amaryllidaceae $14

Amorphophallus konjac voodoo lily
This arum from southeast Asia is widely cultivated for its edible tuber, but we grow it for the huge tropical looking leaves and "snakeskin" stem and try to ignore its beautiful, black, huge but reeking fly-pollinated flowers. (Aroma can be mitigated by rinsing the flower.) Can reach 6 ft tall in part sun to shade with regular summer water. Cold hardy to USDA zone 6.
Araceae $9

Anemone x lipsiensis rock garden anemone
A natural hybrid, this cute little anemone has all the good qualities of the species and few of the bad. No ‘I turned my back and it ate my Hellebores”; no ‘It lifted the sidewalk.’ Large pale yellow flowers on very finely divided stems that carpet the ground in spring. Excellent knitter in the rock garden, rock wall or between stepping stones. Frost hardy to USDA zone 4. Excellent.
Ranunculaceae $12

Anigozanthos ‘Kiwi Sunset’ Kangaroo paws
One of a great number of fascinating kangaroo paws, this iris-like Australian produces foliage to 18” to 2 ft with clusters of tubular, furry, warm-coral-fading-to-peach flowers for much of the spring, summer, and autumn season. A native of sterile sandy soil, they prefer a lean soil mix that is well-drained and bright light. Though prone to ink spot, a blackening of the leaf tips, we consider that part of the fun. Frost hardy to about 20F or a little lower, USDA zone 9, possibly into upper zone 8.
Haemodoraceae $14

Anthericum caryi [Yucca Do T76 101593-76001] cl
Collected by plantsmen John Ferry and Carl Shoenfeld in northeastern Mexico, this wonderful little lily looks like a little grass that sports chlorophytum-like flowers of warm orange for the entire summer season. Easy in the garden in well-drained soil, or even rather poor soil like the rocky cliffs of its native habitat. Enjoys occasional summer water with full sun to dappled shade. Winter dormant. Frost hardy in USDA zone 7.
Agavaceae $12

Arachniodes standishii upside-down fern
Much sought-after and hard to find fern, from Japan and Korea, with handsome evergreen to semi-evergreen fronds from 1-3 ft, almost frilly in appearance, and forming clumps that reach 2-3 ft wide after many years, spreading by underground rhizomes. For light to deep shade with average summer water. Frost hardy in USDA zone 4, to -30F
Dryopteridaceae $22

Arisaema consanguineum - silvered centered
Shared with us some years ago by our friends the O’Byrnes, these graceful jack-in-the-pulpits rise to nearly 3 ft in late spring with narrow graceful leaflets centered indeed silver. Flowers are deep cinnamon. Adds to its beauty by clumping quickly. Dappled shade is best with consistent summer moisture and, of course, decent drainage. A wonderful addition to the woodland garden or container. Frost hardy in the ground to 0F, USDA zone 7 or below.
Araceae $17

Arisaema ringens f. sieboldii
Impress your friends, scare the neighbors with this must-have, Japanese, jack-in-the-pulpit, with large, tropicalismo-esque trifoliate leaves to over 18" and striped flowers in mauve, white and black. Clumps rather quickly. Best in the woodland garden with moist, fertile soil. Comes up late March and goes dormant in warm weather. A poster child hortisexual plant. Frost hardy in USDA zone 7. One of the easiest yet, strangely, seldom available.
Araceae sold out

Arisaema taiwanense - silver leaved formCobra Lily
The pewter-leafed form of this iconic cobra lily. An umbrella of steely leaflets above the sinister black purple flower on a python stem. Later pollinated plants (they can be either sex, or both, at will) will produce red berries that persist through the winter. For shade to dappled shade in rich soil with average of summer water. Frost hardy in the ground in upper USDA zone 6, possibly lower.

Arisaema tortuosum whipcord cobra lily
Surprising, strange, and wonderful Jack-in-the-pulpit from the Himalayas, making its garden appearance in June as a 4 ft tall stalk (actually a petiole!) from which two palmate green leaves unfurl, topped by the green flower, the "Jack" displaying a loooong, tongue, to 12+", that extends high above the "pulpit." Good soil and average summer water in light shade to shade in hottest climates. Frost hardy to at least USDA zone 6.
Araceae $19

Arisaema triphyllum 'Black Jack'
Who wouldn’t love a black Jack-in-the-pulpit? Handsome leaves are green on the undersides and dark, dark, dark on top with striking green veins and stems -- attractive when backlit. Leaves emerge in spring in clumps to 1 ft tall, quickly presenting a “pulpit” flower with dark maroon stripes on the inner surface. Very nice! Prefers light shade and abundant summer water. Frost hardy in USDA zone 5.
Araceae $35

Aristea major
An intriguing group of blue-flowered irids, mostly from South Africa. This species we once thought too tender for permanent planting in the ground in these parts, but they have thriven for many years now, giving us courage. Easy in average garden conditions, luscious with summer water. Bright green iris-like leaves to 2 ft or a bit more with clusters of sky-blue flowers from spring through fall -- all from the small inflorescence, so don't cut them back. Evergreen to the upper teens F, upper USDA zone 8; regrowing, especially with mulch, from 10F or so. Bright light is best. We find these most outstanding when planted with yellow foliage nearby.
Iridaceae $14

Aristolochia californica [Red Bluff, CA]california pipevine
This western native Dutchman's pipe, indigenous through western California and southwest Oregon, is a vine to 8 ft or so or a happily scrambling specimen. Deciduous, with 3”, heart-shaped leaves and olive green stems that are quite attractive in their winter leaflessness. In spring and sometimes beyond into summer, light flowers appear -- the Dutchman's pipes of the common name -- often mottled or centered a maroon brown. Sun to part shade with afternoon protection in the hottest climates. Happy with extreme summer drought. Cold hardy to USDA zone 7. Host to the gorgeous blue Pipevine Swallowtail butterfly.
Aristolochiaceae $12

Artemisia ludoviciana 'Valerie Finnis' Western mugwort
From the famed British plantswoman of the same name, this lovely evergreen perennial, from about 18" to 4 ft tall, is perfect for a sunny location with very good drainage. Both erect stems and leaves are silver-white, adding contrast and texture. Summer flowers are yellow on tallish stems, not significant. Half to full sun. Though drought tolerant, occasional summer water replenishes the abundant foliage. Plants can be sheared to reshape. Frost hardy in USDA zone 6. Much prettier than its common name would suggest.
Asteraceae $11

Arum palaestinum black Calla lily
One of many delicious arums from the mountains of the Middle East and one that clumps for us instead of eating the garden. Winter growing with shiny, bright, 8-12” leaves and velvety, late winter flowers opening black and aging to rich, dark maroon. Seems tolerant of summer moisture or complete summer drought. Good for shade in the dry border. Intact in our garden after the December 2008 cold spell to 20F. We reckon cold hardiness to at least mid USDA zone 7.
Araceae $14

Arundo donax ‘Variegata’ variegated giant reed
An especially good variegated selection, the green foliage stripped in creamy white. This vigorous grass, straight-stemmed to 8 ft, forms clumps to 3-5 ft making a great screen or hedge. Late summer flowers appear as pinkish plumes standing above the foliage. Site in a sunny spot with its feet protected and provide summer water. Evergreen and cold hardy in USDA zone 8. A die-back perennial that can resprout as low as upper zone 5.
Poaceae $12

Asarum caudatum f. album white flowered western wild ginger
Handsome evergreen goundcover, to only 4-6" tall, and spreading into clumps by underground rhizomes. Leaves and roots are are aromatic when crushed. Spring flowers are greenish white in this form, a nice contrast to the dark green leaves, though flowers are often hidden under the leaves. Worth searching out. Best in shade in well-drained, humousy soil. Needs water to established and then tolerates some summer drought. Frost hardy to -20F, USDA zone 5.
Aristolochiaceae $14

Asarum splendens orifice ginger
A hardy evergreen ginger from China for a shaded nook. Cyclamen-like foliage, green mottled with with gray-silver, to only 6" tall, spreads moderately by underground rhizomes making a good groundcover for shade. The flowers are also wonderful, sometimes hidden but often upfacing, purple with white markings. One of the best of the genus and worth kneeling for in spring. Shade is best in rich soil with regular summer water. Bait for slugs. Frost hardy in USDA zone 6.
Aristolochiaceae $14

Aspidistra elatior 'Asahi'Cast Iron Plant
A gorgeous selection of the same cast iron plant. Though this isn't the "biggest aspidistra in the world," it reaches about 1/2 to 2/3 the size of typical at about 18" to 25" tall with 6" wide leaves brushed cream especially towards the tips. A stunning garden or container plant that can thrive in the deepest of shade. Best if kept out of direct sunlight especially in hot climates. Frost hardy in USDA zone 8; upper zone 7 with protection. Protect from slugs and snails.
Liliaceae $18

Aspidistra elatior 'Big Bang' cast iron plant
A larger version of A. elatior 'Milky Way', to 3 ft tall with arching, glossy leaves and the signature yellow polka dots, elongated as if stretched. Pretty in the garden or in containers alongside creams and yellows to bring out the contrasting dots. Slow growing, at least in the cool nights of the West Coast. Prefers rich soil and consistent summer moisture in shade to deep shade with at least afternoon protection from bright light. Grows in the darkest imaginable areas. Frost hardy in USDA zone 8 to upper zone 7 with protection.
Liliaceae $18

Aspidistra elatior 'Milky Way' Cast Iron Plant
An old-fashioned variant of the rugged cast iron plant, in commerce for a long time but not often seen. Narrow, shiny green leaves, to 18" to 2 ft tall, are decorated with yellow polka dots, many slightly elongated as if just transitioning into warp drive. Very pretty in garden or container especially when paired with cream foliage to accent the dots. As with the others, slow growing, at least in the cool nights of the West Coast. Consistent summer moisture in deep shade or at least afternoon protection from bright light. Otherwise grows in the darkest imaginable areas. Frost hardy in USDA zone 8 to upper zone 7 with protection.
Liliaceae $18

Aspidistra elatior ‘Variegata’cast iron plant
The solution to your shadiest spot: a cast iron plant with lovely white stripes on dark green leaves, to 2+ ft tall. Hardy outdoors in light to deep shade with normal summer water, they prefer good drainage. Regular summer water for best appearance, though tolerant of long dry periods. Clumping plants, they are somewhat slow growing, doubling their size in a few years. Also fab in a container. Frost hardy in USDA zone 7.
Liliaceae $18

Aspidistra lurida ‘Ginga’ cast iron plant
Often sold in the United States as 'Milky way", this one in no way resembles that one. The Japanese name 'Ginga' means "spotted and streaked" and this plant is that. Stunning purple flowers, often called "spider eggs", appear in early spring but can only be appreciated by lying belly down in an accommodating gardener's garden. Worth the trouble. Part shade to deep shade with little or no summer water necessary. Frost hardy in USDA zone 7.
Liliaceae $16

Aspidistra minutiflora cast iron plant
One of the more intriguing of the cast iron plants, a genus on which we have become rather fixated, this with very narrow leaves, to 30” tall and only 1/2 to 1” wide, of deep green with a bit of silky blue overlay. Creates graceful clumps reasonably quickly in the woodland garden or in container where the nearly black stem sheaths can be easily observed for hours on end … or at least a second or two. Enjoys ample summer moisture, though, as with other aspidistras, seems to accept being nearly moisture free in dark, cave-like spaces. A perfect addition under shrubs where other plants are not likely to thrive, or in dark entry gardens for instance. Frost hardy to the bottom of USDA zone 8. Has also been offered as Aspidistra linearifolia.
Liliaceae $16

Aspidistra tonkinensis 'Spotty'cast iron plant
A Cistus introduction of a lovely species, this our seedling selection from Southeast China, with graceful, long green leaves, to 3 ft or more, emerging with black sheaths, the leaves humorously spotted almost golden. Thus far frost hardy to upper USDA zone 7. Tolerant of deep shade and drought, but more pleased with ample summer moisture and good soil. We think this is one of the most graceful of all the aspidistras.
Liliaceae $24

Aspidistra typica 'Old Glory' cast iron plant
Small cast iron plant, selected in Sichuan Province in 2002 by Darrell Probst and named by Plant Delights Nursery. To only 15" tall, the wide and shiny green leaves marked by a broad, greenish yellow band down the middle and, especially with age, spreckles and spots adding texture. Slowly forms clumps. As with others of the genus, does well in containers or in the garden in shade to very deep shade, bringing color to dark corners. Tolerates some drought but prefers even moisture in rich soil. Frost hardy in USDA zone 8 to upper zone 7 with protection.
Liliaceae $18

Asplenium ebenoides dragon's tail fern
Rare, small, evergreen fern, native to central and northeastern United States and first discovered growing on limestone cliffs outside Philadelphia. A curiosity for its irregularly divided, triangular fronds, to 6-12" long -- the dragon's tails, that together create small mounds, growing slowly to only 6-8" tall x 8-12" wide. Plant in part to full shade in soil that is consistently moist, well-drained and a bit limey if possible. Frost hardy to -20F, USDA zone 5. Also does well in containers or indoors.
Aspleniaceae $12

Asplenium goudeyi Dwarf Bird’s Nest Fern
This extremely choice, Australian fern is shorter, stiffer, and more leathery than its tropical brethren -- to only 12" tall. Needs warmth, moisture, and light, but protection from the full sun. Can be kept in a container and grown indoors, but Fancy Fronds Nursery in Gold Bar, WA has had one in the ground for six years. Frost hardy in USDA zone 8.
Aspleniaceae $12

Asplenium scolopendrium 'Cristatum' Crested Hart's Tounge Fern
A crested version of the elegant hart's tongue fern. Evergreen, with leathery, bright green, not-so-tongue-shaped fronds, crested on the tips and crinkled on the edges, in clumps to 1-2 ft tall and wide. A European native, for shady, woodland areas in rich, well-drained soil and average summer moisture. Frost hardy in USDA zone 6.
Aspleniaceae $15

Astelia banksii - compact formshore astelia
Graceful member of the genus, this form producing spring-green, arching leaves, to only 2 ft, with striking, silver undersides and, in spring and summer, cream to chartreuse flowers. Tolerant of salt spray for coastal gardens and easy in any garden with regular summer water and full sun to dappled shade. Frost hardy to the mid teens, mid USDA zone 8; has survived 10 to 12F with some protection.
Liliaceae $16

Astelia nivicola 'Red Gem'
Our favorite nivicola collection, again from New Zealand, forming clumps to 2 ft wide by roughly 18" tall with numerous leaves, all coated with a soft silver fur, that become deep red, almost burgundy, with light and frost in winter. Very striking! This has been one of the toughest creatures, not having received frost damage even in the 14F, arctic extravaganza in 1996. Also an amazingly good container plant where burgundy tones in rosette-forming plants are hard to come by. Even summer moisture in bright light for best color, though accepting of shade. Tolerant of frost to 10F, USDA zone 8, with reports of near 0F out of the wind.
Liliaceae $16

Aster ageratoides var. ageratoides 'Ezo Murasaki'
An aster that has it all! Compact and sturdy to 2 ft tall and wide, covered in purple flowers that bloom over a very long period and stand up against frost and fall drizzle. Sun to part shade with summer water. Still difficult to find outside collector’s circles and deserves greater presence in the gardener’s autumn palette. Evergreen in USDA zone 8 and root hardy in zone 4.
Asteraceae $14

Astrolepis sinuata wavy cloak fern
A fern that loves sunny dry places. From the desert southwest comes these luxurious clumps gray-sage-green leaves with felty, orange undersides. To 1-2 ft tall eventually and evergreen to semi-evergreen. Full sun to dappled shade with excellent drainage and lean, gritty soil. Best placed where air circulation is good and the roots can remain cool, perhaps in a rock garden. Drought tolerant but enjoys occasional summer water. Cold hardy from 0F, USDA zone 7.
Pteridaceae $14

Aucuba chinense 'Spotty'
A Cistus introduction. Never thought it would happen, but here we are in the midst of an Aucuba phase. This exceedingly useful group of plants, found usually in only a few clones lurking under stairwells, has so much to offer. A graceful, 4 ft, evergreen shrub, 'Spotty' has narrow leaves, to only about 1” x 4” sprayed with yellow polka dots. Excellent for deep, dark, dry shade! Happiest with some summer water in very dry summer places or way back there under the the stairs. Frost hardy as cold as upper USDA zone 6.
Cornaceae $14

Aucuba himalaica
Another evergreen background or filler shrub useful for difficult garden spots, this 4-5 ft shrub with shiny, narrow, 5” leaves grows in any conditions from severe root competition to the darkest garden corners, never skipping a beat. This clone produces orange-red berries in great abundance if a male Aucuba is anywhere nearby. Provide some summer water where dry for best appearance. Frost hardy in upper USDA zone 6.
Cornaceae $14

Aucuba japonica ‘Clear Picture’
Classic evergreen shrub to brighten the deepest shade, this one with clear, yellow variegations on dark green leaves. To 4 ft tall x 3 ft wide, dense and upright with a rounded shape. Easy, thriving in most situations of dappled shade to shade in rich, well-drained soil. Tolerant of some drought once established though perhaps more luscious with summer water. Frost hardy in USDA zone 7.
Cornaceae $15

Austrocedrus chilensis [Cañon Infernillo, Chile] chilean incense cedar
Lovely, drought adapted tree with somewhat weeping branches of light green cast in blue and a narrow, upright form, to 50 ft tall x 15 ft wide, keeps its columnar shape until quite old when the crown may broaden at the top. Bark is orange to darker brown and peels in narrow strips. This high elevation collection from about 4500 ft indicates cold hardiness of close to 0F, USDA zone 7, if provided bright light and good drainage. Reminiscent of our own native incense cedar, Calocedrus decurrens.
Cupressaceae $18

Austrocedrus chilensis RCH 476
This Randall Hitchin collection has turned out to be a doozy, truly extraordinary. From one single seed collection, we have selected not only a variegated plant but also one with very deep blue foliage. These seedlings, though variable, have all turned out to be a much prettier blue than the typical plants in commerce. A lovely western Andean plant, growing in conditions seemingly analogous to the dry rocky slopes of our western cedar, Calocedrus decurrens. Tested plants seem to have a cold limit of just below 0F, upper USDA zone 6. Though adapted to dry summer places, a little extra water speeds them to 18” to 2 ft of growth a year to an eventual 30 ft tall. The symmetrical sprays of branches make a perfect companion for your monkey puzzle (Araucaria araucana) with which they often grow.
Cupressaceae $16

Azara microphylla ‘Variegata’ variegated boxleaf azara
Extremely handsome, small, arching evergreen tree, very slow-growing to 15 ft, with small leaves variegated green, cream and white, and spring flowers that are intensely scented (with the aroma of white chocolate -- or so our employees insist). Site out of full sun in well-drained soil or use in container as a showoff specimen. Frost hardy in USDA zone 8. Can suffer leaf damage below 15F.
Flacourtiaceae $18

Azara uruguayensis
Ranging in habitat from high elevation sites in northwestern Argentina and into Uruguay and southwestern Brazil, this species accepts hot, humid conditions as well as hard frosts into the teens, USDA zone 8. Surprisingly, this clone sailed through temperatures nearing 10F in January, 2010. To 15-20 ft tall with particularly large, rounded, succulent and interesting, subtending leaves. Yellow spring flowers are followed by azara signature berries. Lean soil with good drainage and summer water. Best with protection from hottest afternoon sun.
Flacourtiaceae $16

Baccharis pilularis 'Blue Mound'
A Cistus introduction, from serpentine coastal bluffs in Harris Beach State Park on the southern Oregon coast. This compact male clone grows to only 3 ft high x 5 ft wide with waxy, blue cast foliage. Replete in winter with little pink brushes adorning the entire shrub, this good evergreen, ground-hugging plant makes the various winter pollinators deliriously happy. Us, too. Best in sun and infertile soil with low summer water. Especially happy in coastal conditions. Frost hardy in USDA zone 8.
Asteraceae $14

Beesia deltophylla
Very nice small, evergreen groundcover with shiny, heart-shaped leaves and spikes of white flowers in late summer. Lovely vein patterns add texture to the leathery foliage. Plants form clumps 18” wide x 1 ft tall in dappled shade to full shade. Tolerant of many soils but best planted in areas that are consistently moist and well-drained soil. Creates a good backdrop for other shade loving perennials. Frost hardy in USDA zone 6.
Ranunculaceae $14

Begonia ‘Metallic Mist’ PP19567
Leaves are seriously silvered on this fabulous and totally frost hardy begonia, at least to 0F. he habit is mounding, to 18” tall, with pink flowers in the fall. Likes rich, moist soil, that must drain well, in part shade to shade and prefers to dry a bit between waterings... don’t we all. Frost hardy in USDA zone 6. Plant patents prohibit proscribed propagation.
Begoniaceae $14

Begonia aff. acetosella A1VT 213
This cutey, collected and shared with us by plantsman Tony Avent, has very shiny and particularly paisley-shaped leaves on ever-so-slightly furry stems which are about 3 ft tall. Pearl-pink flowers are displayed over a long season. Like other begonias, primarily for moist soil and shade though this form tolerates a fair amount of sun if well-watered. We have enjoyed this in both container and garden. Resprouts from low USDA zone 8 winters if mulched.
Begoniaceae $14

Begonia aff. acetosella (T.A. 002)
This cane forming begonia collected by Tony Avent in northern Vietnam grows to between 2 and 3 ft in height with silky green triangular leaves, dark stems and masses of pale pink flowers from mid summer until frost. A most attractive shade loving shrub for the mild, damp garden or a lovely container specimen where temperatures regularly drop between 15 and 20 F. Has proven root-hardy in the southeastern US to below 10F if winter mulched. Yet another addition to the growing numbers of hardy garden species. USDA zone 8.
Begoniaceae $14

Begonia aff. sinensis DJHC 700
Received from our friends at Heronswood from a wild collection by Dan Hinkley, this hardy begonia’s stunning foliage shines in its moist, shady nook. Pink and white flowers are an added benefit, of course. No problems overwintering in the shade garden with good drainage. Frost hardy in USDA zone 8.
Begoniaceae $12

Begonia emeiensis DJHC 98479
A Dan Hinkley collection from Emei Shan and a striking addition to the increasingly large repertoire of begonias hardy in USDA zone 6 or above, this with 6-8” succulent, heart-shaped leaves and, in late summer and fall, attractive clusters of luscious pink flowers within the canopy. Shade to afternoon shade in moist conditions. Evergreen into the upper 20s F; deciduous but resprouting handily in early spring after temperatures as low as -10F, USDA zone 6, especially if mulched. A swollen (node) at the end of each leaf petiole can sprout and increase the plant. Easy
Begoniaceae $14

Begonia hemsleyana
Very hardy begonia grown in gardens for many years. Dormant through winter, emerging in June with fuzzy red stems carrying palmate leaves, dark green spreckled white. A very nice texture for the shady, woodland garden, in moist conditions -- but not too moist. A bit of drying before watering is welcome. Requires good air circulation as well. Found at 4-6,000 ft elevation in Yunnan, China, these are frost hardy to USDA zone 7.
Begoniaceae $14

Begonia pedatifida
One of the most hardy and lovely begonias from the highlands of southern China. To 1 ft tall with feathered leaves to about 6", pale green often veined pink with silver markings. Substantial pink flowers appear mid to late season. Best in shade, in rich soil with adequate summer water. Remains green to the mid 20s F and returns in USDA zone 7.
Begoniaceae $14

Begonia richardsonii
Intriguing caudex forming species from summer rainfall South Africa. Grows only to about 18" but quickly forms a caudex of up to 3" giving the appearance of a miniature baobab (Adansonia digitata). Makes us want to create a tiny national park. Ruffled leaves, under 1", are pleasingly undulate and shaded in purples and grays. Small pink flowers complement its stature. Frost hardy to only upper 20s F, upper USDA zone 9, but fine for the protected garden or as a pot specimen.
Begoniaceae $12

Begonia sp. DJHT 99167
Collected some years ago and shared with us by plantsman Dan Hinkley, this Chinese species has been stalwart in our shade garden and hardy, we are told, well into USDA zone 7 in colder climates. Glossy upright leaves to about 5" with the classic paisley shape and copious numbers of shell-pink flowers in mid to late season. Deciduous in the mid 20sF for short periods. Otherwise resprouts quickly in spring. Be sure to mulch rhizomes in colder climates. Moisture and shade lovers.
Begoniaceae $12

Berberis congestiflora RCH 470
Another southern Chilean collection by Randall Hitchin, this a small shrub, to only about 3 ft, with minute, wavy and spined evergreen leaves and tiny little racemes of intense, orange-yellow flowers in spring and occasionally in summer leading to dark blue berries. Makes a dense, easy-care shrub, if only provided soil that is not really rich and an occasional summer rain or hose shower. Full sun for best flowering. Frost hardy in USDA zone 6.
Berberidaceae $14

Berberis darwinii RCH 404
A striking barberry, the flowers, bright yellow-orange on red stems, are showy and cheerful over a long season in spring. An evergreen shrub, this form collected by Randall Hitchin, to 8 ft tall and nearly as wide, with arching branches and spiny leaves, dark green above and lighter below. Native to Chile and Argentina, these handsome plants enjoy full sun to part shade in reasonably well-drained soil with average summer water. Frost hardy in USDA zone 7.
Berberidaceae $14

Bergeranthus jamesii cl 2
Ice plant relative from South Africa, to only about 2” tall in clumps to 5-6” wide with succulent, triangular leaves. In summer, bright yellow, daisy-like flowers cover the the plant. Requires very good drainage in lean soil, sun in all but the very hottest climates, and an occasional watering in summer by hose or monsoon. Frost hardy to 0F, USDA zone 7.
Aizoaceae $8

Beschorneria aff. decosteriana - large green
These seedlings from plants originally collected from Mexico’s Tamaulipas State have grown larger than any others we have tried. The succulent, deep green rosettes reach to over 4 ft wide and high and occasional cherry-red and green flower spikes, to upwards of 10 ft, suggest giant hummingbirds hovering just out of sight. Possibly the best attribute of this wonderful plant -- and the whole genus for that matter -- is its agave-like texture coupled with a willingness to grow in medium shade though perfectly at home in full sun in all but the lowest, hottest places. Occasional summer thunder storms, or the equivalent thereof, simulate its mountain forest home. Frost hardy in upper USDA zone 7, having lost its leaves but recovered from around 10F in gardens…not ours, thankfully.
Amaryllidaceae $16

Beschorneria albiflora
One of the larger members of this genus of agave relatives from northeastern Mexico growing amid oaks, pines, and many other delicious plants. This species forms open rosettes of pale green leaves, to about 3 ft, with flower stalks rising to 6 ft or more, the flowers often red at the base and very pale green, indeed nearly white, at the tips of the sepals. Prefers some summer water where dry. Has performed admirably in our garden in dappled shade and should be frost hardy in USDA zone 8, to about 15F with no leaf damage, resprouting in spring from 10F or so.
Amaryllidaceae $16

Beschorneria septentrionalis false red yucca
Another bold non-agave from northeastern Mexico, producing rosettes to 2 ft of deep green, 4" leaves, the plant resembling a pile of hung-over starfish. The flowering, on red stems, are deep red edged with green and followed by red tinted seed pods. Drought tolerant but loves a little summer water along with excellent drainage and partial shade to full sun. Essentially a USDA zone 8 plant though success has been achieved in USDA zone 7 gardens with occasional protection.
Amaryllidaceae $15

Beschorneria sp. [S. LaPeña, Mex. 8700']
From a 1993 collection in the rugged mountains of Coahuila, Mexico amid many other botanical treasures, comes this strap-leaved, blue-green perennial, to only about 18”, with some of the prettiest flowers to be found in the genus. The stems are red, holding orange red flowers with bases dipped in green. Hummingbird magnets! We are still looking for a likely name. Because of its high elevation habitat at over 8500 ft, it is expected to be frost hardy well into USDA zone 7 and evergreen to 15F. Full sun to medium shade; has succeeded in full shade in very hot climates with occasional summer water for best look. A very nice plant.
Amaryllidaceae $16

Bignonia capreolata 'Atrosanguinea' Red Cross-vine
Lovely evergreen trumpet vine from the southeast, to 15 ft or so with clinging stems for walls or trellis. A colorful creature: the new foliage is tinted burgundy while emerging and the flowers are dark red-orange appearing in spring and scattered through the warm season. Appreciates some summer water in full sun to part shade. Perfectly happy through winters of 0F, USDA zone 7, and surviving only somewhat scathed in –10F, zone 6. A tough little camper.
Bignoniaceae $14

Bignonia capreolata 'Tangerine Beauty' cross vine
Stunning and very fast-growing, vine from the southeastern US, the large, trumpet-shaped, orange flowers cloaking the entire plant in early summer with occasional blooms on into fall. Truly tangerine and truly a beauty. To 10 to 20 ft; needs strong support, climbing by tendrils that can attach to textured walls and cover problem areas. Blooms on old wood so prune immediately after flowering. Full sun to part shade and average summer water. Evergreen in USDA zone 8 and frost hardy in USDA zone 6.
Bignoniaceae $14

Boquila trifoliata RCH 412
A Randall Hitchin collection from the riches of south central Chile, this lovely vine, to an eventual 8 ft, has evergreen, fluted, three-parted leaves, a rich green produce pea-sized, edible fruit. A good addition to the all-too-limited number of smaller evergreen vines available. Tolerant of summer drought, though accepts water with good drainage. Full sun to part shade. Frost hardiness hovers around 10F or so, the line between USDA zones 7 and 8.
Lazardizabalaceae $15

Brahea armata MExican Blue hesper Palm
The leaves are chalky, dusty blue on this most stunning Mexican palm. Slow growing, to 20 ft in a long time. Sun to part shade and lean soil that promotes very, very good drainage for best winter hardiness. Drought tolerant but faster growing with some summer moisture. Roots should be disturbed as little as possible when planting. Easy in USDA zone 9; frost hardy with protection in zone 8 or in pots.
Arecaceae $18

Brahea sp. - super blue/silver
A clumping creature, to 10 ft tall, looking much like Brahea decumbens but with larger leaves and a more extended trunk. These are a mid-elevation collection from central Mexico at the edges of thorn scrub where it meets oak country. Dappled shade to full sun and generous summer fertilizing with water to speed its slow growth. We know it makes a beautiful container specimen but don't yet know its potential frost hardiness. So we can only guess at 20F, the bottom of USDA zone 9.
Arecaceae $15

Buddleja colvilei ‘Kewensis’
Considered one of the best of the buddlejas, this large shrub to small tree, grows quickly to 10-15 ft, with handsome, felted leaves and astonishing, terminal panicles of large, dusky fuchsia flowers in June. Best in full sun and well-drained soil with regular water. Evergreen in mild climates and frost hardy in USDA zone 8.
Loganiaceae $16

Buddleja globosaorange ball tree
To see it in bloom is to covet this cheerful plant, ours a Cistus collection from the highlands of Argentina. To 6 ft tall or so with long, narrow, "woolly" leaves of green-silver-grey and copious, 2" diameter, orange-yellow, puffball flowers.-- fragrant of course. Full sun and well-drained soil with regular water. Frost hardy and deciduous in USDA zone 7; semi-evergreen in upper zone 8 and above.
Loganiaceae $12

Buddleja x pikei 'Hever Castle'
Another delicious hybrid with many fine attributes; one being that it appears to be sterile. Others include a small texture with narrow, dusty green, evergreen leaves and the prettiest lavender-blue flowers, fragrant and in great profusion from spring until frost. A shrub to 5-6 ft tall, one of the best behaved at the buddleja party, having originated at Hever Castle in Kent, England. Sun to dappled shade with reasonable water. Frost hardy to USDA zone 7. Also known as B. x pikei 'Hever.'
Loganiaceae $11

Butia capitata [South Carolina Shell Station] pindo palm
With our travels far and wide around the world to find ever newer plants, exotic collection sites can hardly get better than this. On a road trip to interior South Carolina, having spotted eight lovely pindo palms that had withstood rigorous winters and all the harsh conditions a mini-strip mall can provide, we brought home seeds in several large Slurpee containers. The palms, a pretty silver-blue, were otherwise typical. They should grow to about 15 ft producing lovely arched pinnate leaves that curl upon extension. Bright sun, good drainage, and overhead protection at 12 to 15F, lower to mid USDA zone 8.
Arecaceae $15

Buxus harlandii harland boxwood
Handsome boxwood, to 4-6 ft tall and vase-shaped, with shiny, leathery leaves, narrow and slightly notched at the top. This dense, mounding shrub makes a wonderful hedge, easily sheered to shape. Spring flowers are pale yellow and very inconspicuous. Prefers sun to part shade in well-drained soil with average moisture but quite tolerant of summer drought once established. Frost hardy in upper USDA zone 7.
Buxaceae $15

Buxus microphylla 'Curly Locks'
A most attractive small boxwood, slow growing to 3 ft or so with narrow curled leaves, just as the name would imply, providing wonderful texture for the garden. Evergreen with leaves tinting only faintly to that dead meat look of winter boxwood (ok, so we could have found a better descriptor). This, however, is offset by the typical male cat fragrance given off by most boxwoods....hummmm. Frost hardy to below 0F, into USDA zone 6. And all this can be yours brightening that somewhat shaded spot with a bit of summer water.
Buxaceae $15
