Frost hardy to -10F, USDA zone 6.
Aceraceae $16 4D

Acnistus australis SBH 6129
A wonderful shrubby angel's trumpet. This form, collected by Sean in Argentina, produces a profusion, indeed a plethora of dark blue, bellflowers hanging from each branch in spring and early summer, outstanding against the pale bark and dark leaves. These deciduous shrubs reach 6-8 ft tall and nearly as wide if left untrimmed. For sun to part shade, flowering best with summer moisture but tolerant of drought once established. Root hardy in USDA zone 7 and evergreen in zone 9 and above. Can be coppiced to maintain compactness but the winter structure of nearly white branchlets is an additional attraction,
Solanaceae $12 4D

Acorus gramineus 'Variegatus' grassy-leaved sweet flag
Grassy, iris-like leaves with cream and golden-yellow variegation stand 12-18" tall, forming clumps to 1 ft wide or so, spreading by underground rhizomes. Summer flowers - sedge-like, tiny and green - contrast with variegated foliage. Easy in the garden, they enjoy sun or part shade in the hottest places and moist soils, even tolerating boggy conditions or standing water to 3" deep. Should not be allowed to dry out. Evergreen in USDA zone 8 and root hardy to zone 5.
Acoraceae $6 4D

Adiantum venustumHimalayan Madenhair Fern
Striking maidenhair fern with lacy foliage that emerges bronzy pink and ages to a gentle green that stands out again the black stems. To only 6” tall, spreading slowly by underground rhizomes to form a clump up to 3 ft across. Light shade with plentiful moisture is best and encourages faster growth. Evergreen to the mid teens F, mid USDA zone 8 and root hardy to at least –20F, USDA zone 5. Also does well in containers, indoors and out.
Pteridaceae $11 4D

Agapanthus 'Midnight Blue' lily of the nile
Gorgeous globes of deep blue-violet flowers on 2.5 ft stalks appear in July and August above 18-24” clumps of dark green, strap-like leaves, narrower than other forms. This Irish selection of a South African native loves sun to part shade, plenty of fertilizer in summer, and well-drained soil. Needs water during the growing season but resents too much water at any time. Frost hardy in USDA zone 7.
Amaryllidaceae $12 4D

Agapanthus 'Tinkerbell' dwarf variegated agapanthus
The variegated companion to Agapanthus ‘Peter Pan’ has dwarf foliage -- green with white edges -- and a dwarf flowering stalk of medium blue flowers rising to 18" above the 8" leaves. Useful as container plant especially for its sprightly, variegated look. Enjoys sun to part shade in well-drained soil and average summer water. Evergreen to the mid 20s F, and cold hardy to at least USDA zone 8 and probably colder.
Amaryllidaceae $11 6in

Agapetes serpens
Exotic, epiphytic, blueberry relation from China with gorgeous, red, heavily veined flowers dangling all along the undersides of arching stems for a long period in spring. Evergreen, the new foliage emerges red creating texture and contrast along branches that emerge from a caudex-like base, eventually reaching up to 3-5 ft long. Perhaps best kept in a container for its hardiness -- to 22F or so -- as well as to show off the weeping form, particularly handsome at eye level. Prefers moist, well-drained soil and protection from hot afternoon sun. Tolerates more sun in coastal areas. Cold hardy in USDA zones 9-10.
Ericaceae $14 3D

Agapetes smithiana
Enchanting small shrub, to only 3 ft tall and a bit wider, with small, leathery leaves tightly held on the arching stems and lovely yellow, tubular flowers that droop from the stems particularly in spring but any time of the year. Found in the mountain forests of the Himalayas, these are slow growing in bright light and well-drained soil with protection from frost where temperatures drop below freezing. Very successful in containers. Frost hardy in USDA zone 10.
Ericaceae $14 3D

Agave 'Burnt Burgundy'
Probable hybrid of A. victoriae-reginae and A. pelona, from Gregg Star who chose it for its unusual, smooth, burgundy-tinted leaves with dark margins. Small, to only 1 ft to 18", these slowly form clumps in full to part sun and lean, well-drained soil. Frost hardy so far to a little under 20F, just below USDA zone 9, in our now Eucalyptus-shaded agave patch, but a fine pot specimen in colder climates. (Eucalyptus mulch optional.)
Agavaceae $16 6in

Agave 'Green Goblet'
Selected in the high Sierra Madre Orientale of eastern Mexico by Carl Schoenfeld and Wade Rosch, this form, most likely A. gentryi with a little A. montana thrown in, has 4-5 ft rosettes of fleshy, moss-green leaves beautifully patterned and indented. From pine/oak woodland, it is adaptable to moist soil and even partial shade where autumn leaves won't collect in the rosettes. Thus far has frost been hardy to close to 0F, USDA zone 7. Note: sun and good drainage become more important the colder the climate.
Agavaceae $16 4in

Agave 'Ruth Bancroft'Shark skin agave
Found in the hills near Saltillo, Coahuila, Mexico, where 3 century plants converge (perhaps collide). This selection, from the California garden of Ruth Bancroft, has an exquisitely fine, platinum-colored sheen with no white markings, clearly showing its A. victoria-reginae and A. scabra parentage. To 2-3 ft tall x 3-4 ft wide. For bright sun and well-drained soil with little summer irrigation necessary. Great in containers. Cold hardy to 10F or so, USDA zone 8. Also known as A. ‘Sharkskin’ for its leaf color and texture.
Agavaceae $18 4D

Agave aff. parryi - Sedona, AZ
This flat, rosetted form (arguably A. parryi v. couseii) was collected by friend Pat McCracken between Sedona and Flagstaff Arizona at about 5700 ft. Offsetting while young, these form slowly spreading clumps, each plant up to 25" or more in diameter. Though particularly attractive if planted in bright red sandstone cliffs, any planting combination will do, where light is bright and drainage is very good. More tolerant of summer garden water than other agaves. Since it was found in a cold canyon, we expect frost hardiness between -5 and 0F, USDA zone 6b. A very good container plant as well.
Agavaceae $14 4D

Agave americana 'Mediopicta Alba'white-striped century plant
Beautifully variegated, diminutive form spreading to no more than 2-3 ft, with rosettes of beautifully curved leaves colored a dusty blue-green with a wide creamy stripe in the center. Slowly offsets in bright light and well-drained soil with occasional summer water but lovely as a single plant. As luck would have it, this form is hardier to frost that many, with plants surviving 10 to 15F, USDA zone 8, in soil that is dry in winter. Pull in or cover below 20F or so in areas of winter wet.
Agavaceae $18 4D

Agave bracteosaspider agave
Looking more like a bromeliad, this agave’s lax, spineless leaves are very choice. Polycarpic and rare in cultivation, these plants are found clinging to the high rocky mountains between Saltillo and Monterey in northeastern Mexico growing with pines and, yes, even Douglas fir and they 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.
Agavaceae $16 4in

Agave bracteosa 'Monterrey Frost'Monterrey Frost Century Plant
A 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 6in

Agave dasylirioides
New and obscure little century plants from Oaxaca, Mexico that 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 2D

Agave durangensis
A most beautiful species with very blue leaves, upright and narrowly fluted. Occurs in only scattered locations above 5,000 ft in the Sierra Madre Occidentale in, yes, Durango, Mexico. This form was collected at 8,100 ft - almost directly on the Tropic of Capricorn - from a ridgetop colony amid small oaks, junipers, and pinon pines, very near the southernmost colonies of A. parryi. So far these plants, with good drainage and bright sunlight, have withstood temperatures of about 20F, USDA zone 9, and would probably withstand low to mid teens, zone 8, if protected from excess winter wet.
Agavaceae $15 2in

Agave funkiana 'Blue Haze'
Selected for its striking foliage, the powdery leaves toothed and narrowing to a sharply pointed tip with a pale to nearly white mid-stripe. Rosettes can reach up to 2 ft tall and wide. Sun and well-drained soil required. Drought tolerant but occasional summer water speeds growth and generally enhances the appearance. Frost hardy to 15F, mid USDA zone 8. Otherwise a happy container plant.
Agavaceae $16 4D

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 one might expect. 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 4D

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 also produce an offset or two. Frost hardy in USDA zone 9, these are tender and damaged under 20F.
Agavaceae $15 2D

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 beautiful silver-gray color represented here suggests that A. scabra, the universal partygoer of that region, has come along for the ride as well. Fast growing 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.
Agavaceae $17 6in

Agave gracilipes - Alamagordo, NM 5000 ft
This collection, from seed, represents one of the westernmost populations of this wide-ranging and variable hybrid between A. neomexicana and A. lecheguilla, the offspring sometimes resembling either parent and appearing here as gracile, star-shaped plants with dark spination and the lighter leaf markings of parent A. lecheguilla but with a much neater rosette and bluish color. Sweet! Offsets slowly. Bright light for best color. Quite drought tolerant but more robust with a real or artificial thunder shower every once in a while. Frost hardy in USDA zone 6 with decent drainage. Handsome container plant.
Agavaceae $15 4D

Agave havardianaHavard agave
One of the best and hardiest agaves, with olive-green or, often, dusty-blue, curving leaves in the classic agave shape. Big, robust, and wickedly spined, usually as 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 4D

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. Best if kept out of hottest afternoon sun in well-drained soil with occasional summer water where dry. A fine rock garden creature where temperatures seldom fall to 15F, mid USDA zone 8 and superb in containers where temperatures are too harsh.
Agavaceae $19 6in

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 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 6in

Agave mckelveyana SBH 6708
This, one of our seed collections from the east slopes of the Hualapai mountains of northwestern Arizona at over 7000 ft, is not only a high elevation collection but represents robust plants, with narrow, blue-green leaves forming rosettes to 18 or 20", each fairly quick to offset. Full sun to dappled shade in hot places. Wonderful in rock gardens or as a filler among other larger plants. One of the hardiest to cold, to -10º F, USDA zone 6, and resilient to excess garden moisture provided excellent drainage.
Agavaceae $15 4D

Agave neomexicanaTrailer 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 -20F, USDA zone 5, with good drainage.
Agavaceae $14 4D

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 4in

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 6in

Agave palmeri - Chiricahua Mtns palmer agave
A handsome agave, to 3 ft tall x 4 ft wide, with stiff, blue-green leaves edged with curved, sharp, red-brown teeth and tipped with a long, sharp spine. Native to southeastern Arizona, southern New Mexico, and northern Mexico, this form originated in the Chiricahua Mountains of south eastern Arizona at higher than usual elevations. The flower stalks, produced in early spring after 5 years, bear pale, greenish yellow flowers followed by banana-like fruit. Plants offset, fortunately, as this a monocarpic species that dies after setting seed. Full sun with good drainage is best with only very occasional summer water. Frost hardy to 5F, mid USDA zone 7.
Agavaceae $14 4in

Agave parrasana
This Mexican species is most easily identified by its thick triangular leaves, beautifully marked blue-green in color, arranged in a striking rosette and edged with equally thick brown and white spines. Plants form low dense mounds, each rosette eventually measuring 2 ft x 2 ft and, in time, sending up 12 ft branched flower spikes of warm yellow blushed apricot. Best in mineral soil, sharp drainage, full sun. This represents a high elevation collection at over 8,500 ft that has thus far withstood between 0 and 10F, USDA zone 7, with overhead protection from excess winter moisture. Stunning pot plant or container specimen.
Agavaceae $16 4D

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 4in

Agave parryi var. truncata
Arguably the most beautiful form of the species with its rosette of wide, blue, truncated leaves -- think giant pine cone. Good drainage and the brightest light is best to maintain shape. Sadly this is also the least hardy for of the species, possible in the ground where temperatures seldom and only briefly dip below 15F in mid USDA zone 8. Otherwise makes a fine container specimen.
Agavaceae $18 6in

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, a rich area where we have selected forms of heucheras, Zauschneria arizonica, and numerous desert ferns. Rosettes are 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 are tinted red, making 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 6in

Agave scabratraffic calming agave
Native to north central Mexico and into west Texas, this very rough-leaved and silver-blue species can grow to 3-4 ft, with long, upward-pointing, narrow leaves. Eventually offsets to form clumps. Quite tolerant of summer monsoons, plants require well-drained soil, especially where winters are wet. Our plants represent seedlings from northern colonies where temperatures of 0F, USDA zone 7, are not uncommon. One of the hardiest of the large agaves. Can also be found as Manfreda scabra.
Agavaceae $16 6in

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 6in

Agave schottii shott's century plant, shindagger
Smallish agave, from the eastern Whetstone mountains of southern Arizona, with narrow, upright, green leaves forming rosettes to 18" or so in large colonies. Leaves have a sharp, spiny tip -- easily inserted into the inattentive shin -- and filifers along the leaf margins but no marginal spines. Altogether a yucca-like agave. After 20 years or so, plants produce yellow, tubular flowers on 9 ft stems, dying after seeds set but leaving behind many pups. Native to southern Arizona and New Mexico southward into Mexico, these thrive in hot, dry places where soil is poor and summer water infrequent. Frost hardy in upper USDA zone 7 with good drainage.
Agavaceae $19 4D

Agave toumeyana - Fish Creek Hill, AZ
Representing old seed collections from C&J Nursery, these colonizing plants, from higher elevations of Arizona, quickly offset forming clumps of 5-6" rosettes of narrow, sharp-tipped leaves edged and streaked white and dressed with filifers. Where they are provided excellent drainage, plants have proven frost hardy to 0F, USDA zone 7, but might be protected at 10 to 15F, zone 8, just in case. A fine pot plant.
Agavaceae $16 3D

Agave toumeyana var. bellaToumey's century plant
A rare and unusual plant with particularly dense rosettes, to 1 ft x 1 ft, of narrow, dark green leaves with striking white markings and decorative filifers or threads as 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 -10F, USDA zone 6, or below in dry soil.
Agavaceae $16 4in

Agave utahensis utah agave
This collection from 7000 ft in the mountains south and west of Grand Canyon has particularly large blue-gray rosettes of spine-tipped leaves edged with hooked spines and could, perhaps, be A. utahensis var. kaibabensis. As with their close relatives, 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 $14 4D

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 4in

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 an artichoke), 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 4in

Agave victoriae-reginae var. compactaQueen Victoria Agave
A beautiful, compact form of an ever-popular species, each olive-green rosette to only 6" or less in width, made up of blunt, black-spined leaves marked with wide, silvery white striations. Begins to offset and form clumps in a year or so in bright light with 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 6in

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 4D

Agave x leopoldii
Compact and architectural century plant brought to us by Yucca Do Nursery, the narrow, slightly curved leaves with a gray-blue-going-green sheen complete with a few stripes and polka dots.

Frost hardy in USDA zone 8b, to 15F or so and as low as 10F if protected from overhead moisture.
Agavaceae $16 4in

Akebia quinata 'Brocade'
Five-leaf akebia with fragrant flowers, interesting fruit, and variegated compound leaves in a brocade of white, cream and green, the white turning rose in winter, this form remaining more evergreen than the species. Purplish, 3-petalled flowers appear in spring followed by 4" purple pods - think large, purple, lima beans - though vines do not always fruit in cultivation. A handsome, fine-textured vine, to 12-25 ft tall, in sun to part sun with regular summer water. Can be used as a vigorous, scrambling ground cover as well. Easily frost hardy to -20F, USDA zone 5.
Lardizabalaceae $14 3D

Aloe aristata Torch Plant
Haworthia-like creature from high elevations of South Africa forming rosettes to 5-6” with each leaf spiked and mottled with cream zigzag markings. Slowly offsets, clumping to form wonderful architectural patterns. Dappled to full sun, decent drainage, and summer water where dry. Probably the most cold hardy, non grass-like Aloe, accepting at least 10F, USDA zone 8, and below into upper zone 7 when planted in the ground. Possibly even lower if kept dry in winter.
Xanthorrhoeaceae $14 4D

Aloe polyphylla spiral aloe
One of the most endangered Aloe species, endemic to the high plains of the landlocked South African country of Lesotho at over 10,000 ft. Succulent leaves, pointed and toothed, form a single rosette, to 1 ft tall x 1.5 ft wide, developing a wonderfully distinct spiral pattern as plants mature. Pink flowers appear on a 2 ft stem in early summer. Best in cool sun or part shade with abundant summer water. Accustomed to damp summers and dry winters, it is also one of the hardiest aloes, to 10F, the bottom of USDA zone 8 and lower if kept dry in the winter.
Xanthorrhoeaceae $24 4D

Alstroemeria 'Glory of the Andes'
An unusual Peruvian lily in that the flowers, a lovely gold with maroon markings, are also slightly sweet and the leaves are variegated, green edged in creamy yellow.

This cultivar is well-behaved in the garden and doesn't spread. Frost hardy in USDA zone 7.
Alstroemeriaceae $12 4D

Amarygia [hybrids]
Amaryllis belladonna X Brunsvigia josephinae crosses from plantsman Wayne Roderick with long, strappy leaves to 2 ft that die back in summer. In late summer early fall a 2 ft stem appears producing clusters of very fragrant flowers in colors that vary from pure whites to dark pinks. These are best in a spot that receives bright light and little summer water. Frost hardy to a bit below 20F, upper-upper USDA zone 8 and best in containers in areas of prolonged periods below freezing.
Amaryllidaceae $15 4in

Amaryllis belladonnaNaked 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” tall -- “naked” since the strappy leaves that appeared in winter have usually died back during the dry summer. Definitely a beautiful lady. Best in a Mediterranean climate with summer heat, good drainage, and very little summer water. Frost hardy in USDA zone 8 and into zone 7 with a bit of mulch.
Amaryllidaceae $14 4in

Anisodontea scabrosacape mallow, false mallow

The foliage is golden, often on red stems, and dazzling on this big and bold perennial, quickly to 3 ft tall and wide, first discovered in a department store in Japan by nurseryman Barry Yinger. Spikes of aralia type white flowers in summer are followed by purple-black berries. Lovely in a woodland, planted in front of darker foliage, say broad-leaved evergreens, or under planted with such lovelies as black mondo grass (Ophiopogon planiscapus 'Nigrescens'). Enjoys consistently moist soil and a bit of shade at least in the hottest climates. Frost hardy to USDA zone 4.
Araliaceae $22 4D

Arbutus arizonicaArizona Madrone
A small, delicate tree, to 15-20 ft in the garden and possibly taller with great age. As with others species, the leaves are glossy dark green with paler undersides, and the flowers are white to pale pink urns that appear in early spring and produce orange fruit lasting into winter. Young bark peels to a somewhat patchy cream color and older bark is mostly gray and plated with large areas of exposed reddish patches. Very picturesque. Though found in dry regions of the southwest and drought tolerant, this tree also enjoys regular garden water, but requires well drained soil. Frost hardy easily to 10F, USDA zone 8.
Ericaceae $16 4D

Arctostaphylos 'Lutsko’s Pink' manzanita
Evergreen shrub, upright to 4-7 ft tall, with a dense habit and handsome foliage of glossy green leaves. Spring flowers are typical manzanita small bells in abundant clusters of white blushed with pink. Best in full sun, lean and well-drained soil, and little to no summer water once established. A mixed hybrid including at least A. densiflora in its parentage, this was originally grown in a Lafayette, California garden and introduced by the designer, Bay area plantsman Ron Lutsko. Frost hardy to 10F, bottom of USDA zone 8.
Ericaceae $14 4D

Arctostaphylos 'Red Stem'
These vigorous plants represent a lovely clone of A. manzanita and A. patula found, in this case, near Whiskey Town Lake in northern California. Vigorous and upright, to 6-8 ft tall, with upheld, shiny leaves on stems that are, indeed, red, and the palest of pink flowers in winter and early spring. Given their source at a moderate elevation of only about 300 ft, this form is more adapted to gardens at low elevation. Best given well-drained, mineral soil, full sun to dappled shade, and care with summer garden water. Frost hardy in USDA zone 6b.
Ericaceae $16 4in

Arctostaphylos canescens x viscida SBH 7625
From the edge of serpentine in the Siskiyou Mountains of southwestern Oregon, comes a very compact shrub with upright leaves showing the furriness of A. canescens and the well ... viscidness of A. viscida. The leaves are an eerie silvery blue, ever so slightly tinted red in winter, and the flowers are light pink appearing from mid winter to early spring. Though these appear to be rather garden tolerant, we still recommend little summer water. Frost hardy in USDA zone 7, possibly colder having come from a high elevation.
Ericaceae $15 4in

Arctostaphylos glandulosa 'Cave's Pink'
A Cistus introduction. A long underused manzanita with a native range from Baja to Oregon, this selection, from just southwest of Oregon's Caves National Monument, grows to 6 ft with mahogany bark, peachy pink flowers in late winter to spring all amid pink-tinted blue leaves. Can you believe it? Basal sprouting, so, unlike other manzanitas, can be cut back if you must. Fairly tolerant of garden water if the soil is well-drained. Frost hardy in USDA zone 7.
Ericaceae $16 3D

Arctostaphylos glandulosa 'Rogue Gem'
A Cistus introduction. Another of our series of A. glandulosa, this, from the reaches above Oregon's Rogue River canyon, spreads to a multiple stemmed mound, 3 ft tall x an eventual 6 ft wide, with deep chocolate brown stems, glossy green leaves, and very pale pink flowers from late winter through late spring depending on weather. Can be cut back. Dappled shade to bright sun with decent drainage. Tolerant of some summer irrigation. Frost hardy in USDA zone 7.
Ericaceae $16 3D

Arctostaphylos hispidula 'Gasquet Jade'
A Cistus introduction. This particularly small leaved clone reaches to 5 ft or more, eventually forming a scaley, red, arched trunk with tightly clasped, shiny green leaves of under 1/2" and, from winter to early spring, cheery pink flowers. Though more tolerant of summer moisture than most manzanitas, we still recommend low summer water in mineral soil and full sun. Frost hardy in USDA zone 8a.
Ericaceae $15 3D

Arctostaphylos hookeri 'Green on Black'
A Cistus Introduction. This compact clone from the Huckleberry Hill area of California's Monterey County is another in a great series of this most useful garden shrub. To only 18" high and wide, with particularly round, shiny green foliage and abundant, small pink flowers in late winter. Tolerant of both sand and clay, these like a bit of summer drought but are not incredibly happy over 100 F in particularly hot inland places. Works well as an understory to a larger arctostaphylos or as a fine ground cover where the leaf form and the wiry blackish stem can be seen. Frost hardy in USDA zone 8.
Ericaceae $15 3D

Arctostaphylos manzanita 'Ione Snow'
From the foothills southeast of Sacramento comes this 12-14 ft, graceful, miniature tree with mahogany-red bark, gray-green leaves, and white flowers December through February. One of the easiest manzanitas to grow in all but the heaviest of soils. Full to part sun. Best to watch summer water --eg, not too much. Great for winter pollinators. Frost hardy in USDA zone 7b.
Ericaceae $18 3D

Arctostaphylos manzanita 'Tehama Green'
A Cistus Introduction, found near savannah in the northeastern Sacramento Valley. One of the largest manzanitas, this handsome selection reaches to 15 ft or more with a trunk that can be over 8" in diameter. A striking small garden tree with pointed green leaves and, from December through February, white flowers with a pink base. Perfect where an Arbutus menziesii won't fit. Likes the same lean conditions as most other manzanitas but is more tolerant of some summer water. Frost hardy in upper USDA zone 7.
Ericaceae $15 4D

Arctostaphylos morroensis 'Nevin's Gray'
Named by Cistus Nursery, but actually introduced via a batch of seedlings from the infamous horticulturist Nevin Smith. Native to fossilized sand dunes just east of Morrow Bay in south central California, these pearly gray leaved, mahogany-stemmed, pale pink flowered beauties mound to about 3 to 5 ft wide, this selection remaining particularly compact and silvery. Can also be lightly trimmed. If you do not own a fossilized sand dune, then any well-drained soil will do. Frost hardy in USDA zone 8. Careful with summer water.
Ericaceae $16 2D

Arctostaphylos patula SBH 7468B
Another evergreen shrub from where the tree manzanita, A. manzanita, comes in contact with the snow mat. This, to three feet or a little more, has glossy green leaves and white flowers in January. Tolerant of heat and drought. Has performed well in our garden, though it is slow growing. Wonderful in contrast with blue-leaved manzanitas. Full sun to part shade, with mineral soil and little summer water. Frost hardy to 0F, USDA zone 7.
Ericaceae $16 4D

Arctostaphylos silvicola SBH 7491 bonny doon manzanita
A Cistus collection from Bonny Doon, California of this rare and endangered manzanita, endemic to California's Santa Cruz Mountains. A large, evergreen shrub that can reach 10 ft tall x 20 ft wide at maturity, these have smooth stems with dark red bark and pale, gray-green, somewhat woolly leaves that are especially silvery, justifying a second common name, ghost manzanita. Summer flowers are white as well. Full sun to light shade, in lean soil with excellent drainage. Tolerant of occasional summer water once established if temperatures are not too hot. Frost hardy to 10 to 15F, USDA zone 8.
Ericaceae $15 4D

Arctostaphylos stanfordiana SBH 7658
A lovely plant, from northern Lake County, California in dry shady soil, reaching to 4 ft tall with a rounded form and glossy leaves with a faint trace of bluish indumentum indicating some blood of nearby A. canescens. Mid-winter flowers are nearly white. For full sun and well-drained soil. Tolerates some summer water but we recommend weaning in September to avoid lush new growth going into cold weather. Frost hardy in USDA zone 7.
Ericaceae $15 3D

Arctostaphylos x mewukka 'Blue Point'
This selection, another choice by Allan Taylor from a lovely group of natural hybrids in Eldorado County California, is an evergreen mounding shrub, to 3 ft tall or a bit more, with particularly large pale blue leaves, to 3", on contrasting mahogany-red stems, to 4 ft, with peachy pink flowers in profusion from late winter to mid spring.

Arisaema candidissimumPINK FLOWERED COBRA LILY
A cobra lily that does well in sun to light shade. This from China sends up flowers stalks in late spring to early summer topped with a pink pitcher flower, sweetly fragrant and beautifully striped with white veins. Two huge, three-lobed leaves, up to 2 ft across, follow to open beside the exotic flowers. A must have plant! Easy in sun to light or dappled shade where soil is well-drained, even rocky, and somewhat dry. Offsets quickly when happy. Frost hardy in USDA zone 5.
Araceae $22 4D

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 4in

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 4in

Aristolochia fimbriataDutchman’s pipe
Small Dutchman's pipe from Brazil to northern Argentina, a prostrate, deciduous ground cover to only 6" tall and 2-3 ft wide, the leaves heart-shaped with prominent, pale, netting following the veins. The exotic flowers, produced all summer, are striking, strong, curved green tubes, 1" across, with long hairs and interiors that are purple-brown, veined yellow. Good for hanging baskets where the flowers can be seen. Average summer water in gritty or sandy soil in sun to part shade in hottest climates. Evergreen where temperatures only dip into the 20sF. Deciduous with good autumn color at lower temperatures. Root hardy in USDA zone 7.
Aristolochiaceae $12 4D

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, but not significant. Fine in 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 $8 4D

Arum palaestinum black Calla lily
One of many amazing 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. Remained intact in our garden after the December 2008 cold spell to 20F. We reckon root hardiness to at least mid USDA zone 7.
Araceae $14 4in

Aspidistra 'Singapore Sling' cast iron plant
This lovely creature, found in a market in Singapore (we believe) both by Barry Yinger and Hayes Jackson, grows to 3 ft or more with only 1-2" wide leaves of deep green, strikingly polka dotted cream yellow. Very spiffy even in deepest darkest shade. Summer water to establish and regularly thereafter for fastest growth though tolerates dry shade as well. As many others, this one is slow growing and we are happy to finally have enough to share. Despite its origins has been frost hardy in the garden at least into USDA zone 8. Also makes a lovely container specimen for medium to low light.
Asparagaceae $22 4in

Aspidistra elatior 'Asahi'Cast Iron Plant
A gorgeous selection of a 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.
Asparagaceae $18 4D

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.
Asparagaceae $18 4D

Aspidistra tonkinensis - all green formcast iron plant
An all green form of this aspidistra species from Southeast China, with graceful, narrow, arching leaves, to 3 ft or more, emerging with black sheaths. These are vigorous growers, appearing earlier in the spring and seemingly more frost tolerant than the species. Best in shade to deep shade and, though accepting of drought, prefers regular summer water and rich soil. Frost hardy to the bottom of USDA zone 7.
Asparagaceae $16 4D

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.
Asparagaceae $18 4D

Asplenium goudeyiDwarf 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 6in

Astelia nivicola 'Red Gem'
Our favorite A. nivicola collection, New Zealand natives, forming clumps to 2 ft wide by roughly 18" tall with numerous leaves all coated with a soft silver fur and turning 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 our 14F, arctic extravaganza in 1996. Also an amazingly good container plant where burgundy tones in rosette-forming plants are hard to come by. Prefers 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.
Asteliaceae $16 4D

Aster laevis 'Calliope' michaelmas daisy
Lovely, lilac-blue aster for late summer color, this is an old cultivar from 19th century England with glossy leaves -- rather than the typically hairy aster leaves -- on black stems that barely show among the dense clusters of flowers lasting through the autumn months. A tall cultivar, these can reach 4-6 ft tall in slowly spreading clumps to 2 ft wide. Sun to part shade with regular summer water. Frost hardy in USDA zone 4.
Asteraceae $12 4D

Aucuba 'Gold Mound'
Yes, we have said before that aucubas are cool. This cultivar, selected and named by plantsman Ted Stephens of Nurseries Carolinianus, reaches only 3 ft or so with a rounded habit, scalloped and rounded 5" leaves speckled and streaked with gold and cream - almost appear entirely golden. Berries are orange turning nearly red in autumn and winter especially if a female clone is nearby. Great for dry shade (such as under dusty stairwells) or as a long lived container specimen. Frost hardy in USDA zone 6.
Garryaceae $16 3D

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.
Garryaceae $14 4D

Aucuba himalaica var. dolichophylla
Sweet shrub to small tree with 5", evergreen leaves, long and narrow and, in this form, particularly prominent cream-yellow spotting over the dark green leaf surface -- just enough to create a texture moment. Useful in otherwise difficult conditions, from the darkest garden corners to places where root competition is severe. These can reach small tree size, but remain within the 8-10 ft range in the garden, easily kept smaller. Part to full shade serves best in rich soil with summer water for best appearance though some drought is tolerated. Frost hardy to just below 0F, upper USDA zone 6.
Garryaceae $16 4D

Austrocedrus chilensis RCH 476 chilean cedar
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 4D

Azara integrifolia
We occasionally obsess about azara, including this Chilean species, a large shrub or small tree that is a bit gawkier than others, but its intensely fragrant, yellow powderpuff blooms in spring far outweigh petty physical flaws. Easily to 12 ft or so and up to 30 ft over a long time, the canopy becomes denser in age, with very dark green, leathery leaves and fruit that birds love. Sun, good drainage and at least occasional summer water. Frost hardy to USDA zone 8.
Salicaceae $12 4D

Azara microphylla 'Variegata'variegated boxleaf azara
Extremely handsome, small and arching, evergreen tree, very slow-growing to 15 ft, with small leaves variegated green, cream and white, and, in late spring, tiny spring flowers that are intensely scented (with the aroma of white chocolate -- or so our friends insist). Orange berries follow for autumn interest. Site in cool sun or part shade in well-drained soil with regular summer water. Can be used in container as a showoff specimen. Frost hardy in USDA zone 8, suffering possible leaf damage below 15F.
Salicaceae $18 4D

Beesia deltophylla
Very nice small, evergreen groundcover from China 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 4D

Begonia hatacoa var. meisneri
Tender begonia with spectacular, silver leaves, the veins widely marked in dark green on top, the whole pale underneath. The flowers are lovely as well, white with petals blushed pink. For pot culture outdoors and wintering indoors. Rich soil in part to full shade with plenty of water. A good accent plant in mixed containers or alone. To only 14" tall. Frost hardy in USDA zone 10.
Begoniaceae $14 6in

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 4D

Begonia pedatifida
From the highlands of southern China, this is one of the loveliest and hardiest begonias. To only 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 resprouts in USDA zone 7.
Begoniaceae $14 4D

Berberis calliantha black-berried barberry
Good foundation plant or accent for the garden, this evergreen shrub, to 3-5 ft tall x 3 ft wide but easily trimmed, has small, holly-like leaves, dark green and shiny, contrasting with the reddish brown stems. Spring flowers are light yellow, inverted cups, nearly 1" across; autumn berries are blue-black as the common name suggest. Easy in sun to light shade with some summer water. Frost hardy to 0F, USDA zone 7.
Berberidaceae $16 4D

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.
Agavaceae/Asparagaceae $16 6in

Beschorneria decosteriana
One of the more robust species of this agave relative, this collection is from the high mountains of northeastern Mexico, growing in the shade of oaks and pines. Leave are 5" wide in rosettes, each stretching to over 3 ft. And flower spikes are 6 ft tall or more with astoundingly red stems, red and green flowers, and pink-blushed seed pods! Drought tolerant but loves a little summer water. A bold-textured garden plant in dappled shade to full sun where temperatures seldom drop below 15F, mid USDA zone 8. Plants have recovered quickly from temperatures as low as single digits, zone 7, provided good drainage and a wee bit of overhead protection.
Agavaceae/Asparagaceae $16 4D

Beschorneria septentrionalisfalse 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 flowers, held on red stems, are a deep red edged with green and produce red tinted seed pods. Hummingbirds love them! People too. 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.
Agavaceae/Asparagaceae $15 4D

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.
Agavaceae/Asparagaceae $16 4in

Orchidaceae $14 4D

Bomarea aff. edulis JSM
This Oaxacan collection from Josh McCullough is a 6-8 ft vine adorned in mid to late summer with vibrant orange trumpets framed by lanceolate, deep green leaves. Stands out particularly well when combine with and and supported by other evergreen vines. Deciduous with frost but rebounds in the following spring. Prefers medium shade of cool feet and sun on its face. Enjoys summer water. Best to mulch where temperatures drop below 20F. Frost hardy in USDA zone 7.
Alstroemeriaceae $15 3D

Bomarea x Alstroemeria
A bit of a botanical anomaly, this so far nameless cross, done by both Calvor Palmateer and Martin Grantham, has produced upright perennials with blue-green leaves and tubular flowers exhibiting shades of pink, orange, and even a little mauve. They have been non-seed producing clumpers in the garden and reliable for several years now, happy with bright light and a bit of summer water. Frost hardy to the bottom of USDA zone 8.
Alstroemeriaceae $14 4D

Buddleja colvileisummer lilac
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, deep rose flowers blooming for several weeks in summer. Very lush and lovely. This species resents the severe pruning that keeps its cousins smaller, so provide lots of room for this large, gorgeous creature in full sun and well-drained soil with regular summer water and protection from wind. Evergreen in mild climates and frost hardy in USDA zone 8. Resprouts from the roots in zone 7.
Scrophulariaceae $14 3D

Buddleja colvilei 'Kewensis'
A very old cultivar of this "best of the buddlejas", selected at Kew Gardens for it's darker-than-the-species red flowers in lovely and lush terminal panicles during the summer. Same pointed and felted leaves as the species and a similar size, e.g. quickly to 10-15 ft tall, so a very large shrub to small tree needing lots of room. (This species resents the severe pruning that keeps its cousins smaller.) Best in full sun and well-drained soil with regular water and protection from wind. Evergreen in mild climates and frost hardy in USDA zone 8. Resprouts from the roots in zone 7.
Scrophulariaceae $16 4in

Bupleurum fruticosum
Graceful evergreen shrub from southern Europe and the Mediterranean regions with shiny, dark blue-green leaves, prominently veined, on branches that become ever more graceful, bending under their own weight as the plant reaches its mature height of 4-5 ft. Yellow flowers in 3-4” umbels add contrast from July to September. Thrives in sun to part sun with well-drained soil of average fertility. Drought tolerant, so little summer water once established. Very tolerant of salt spray in coast areas. Cold hardy to USDA zone 6.
Apiaceae $14 3D

Bupleurum spinosumspiny hare's ear
This is one of the smaller bupleurum species, forming a small mound of dense, evergreen foliage, blue-green and spine-tipped, remaining under 2 ft tall. In spring plants are covered with angular sprays of teenyweeny yellow flowers that are both striking and sculptural in the garden. Tolerates dry summer conditions once established, requiring little summer water in full sun and gritty soil that drains well. Frost hardy to -20F, USDA zone 5.
Apiaceae $14 4D

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 4D

Buxus microphylla var. japonica 'Variegata' - dwarf form
Well...kind of dwarf anyway. Given to us several years ago by the late, great gardener Jane Platt, this compact 6-8 footer has a naturally pyramidal growth and pleasingly cream and green leaves with nary a reversion to date. Excellent and hardy as a container or hedge plant. And easily shorn if a more formal look is desired. Sun to dappled shade with regular summer water at least until well established. Frost hardy in low USDA zone 6, we hear, possibly colder.
Buxaceae $12 4D

Buxus sempervirens 'Golden Swirl'common box
A collection from a lone surviving shrub in the shade of an ancient pecan in a North Portland “garden”, this 8 ft boxwood has a tall, rather narrow habit, with upright branchlets and a pleasing creamy-gold variegation throughout the leaves. Drought tolerant and vigorous. You should have one. We would like to see it used as good garden furniture. Considering its “habitat” it must be very drought tolerant and, from the original plant’s appearance, able to withstand occasional pruning with chainsaws. Frost hardy in USDA zone 6, at least.
Buxaceae $14 4D
