Abelia x grandiflora 'Margarita'margarita abelia
New and interesting abelia with variegated leaves, green with bright yellow margins, on red stems, dressing up a smallish shrub, expected to be 4 ft tall and wide. A cheerful addition to the garden. Flowers are typical of the species, beginning in May and continuing sporadically throughout the season. Best in sun -- they tend to be leggy in shade -- with average summer water. Frost hardy to -20F, USDA zone 6.
Caprifoliaceae $014 4D

Abutilon 'Savitzii'flowering maple
One of the few abutilons we sell that is quite tender. Grown since the 1800s for its wild variegation -- the leaves large and pale, almost white with occasional green blotches -- and long, salmon-orange, peduncled flowers. A medium grower, to 4-6 ft tall, needing consistent water and nutrients in sun to part shade. Winter mulch increases frost hardiness as does some overstory. Frost hardy to 25 F, mid USDA zone 9. Where temperatures drop lower, best in a container or as cuttings to overwinter. Well worth the trouble!
Malvaceae $009 4D

Acanthus mollis 'Hollard's Gold' golden bear’s breech
An outstanding selection of bear’s breech with shiny golden-green leaves growing in clumps, to 2 ft tall x 3 ft wide, and taller spikes of purple and white flowers rising above in early summer. Develops the richest color in a bit of shade, even dry shade, though plants may go summer dormant in too much drought. Otherwise accepting of summer water. Remains evergreen in mild winters and root hardy in USDA zone 7b.
Acanthaceae $012 4D

Acanthus mollis 'Tasmanian Angel'variegated bear’s breech

Acanthaceae $012 4D

Acer oblongum var. concolor 07SM017 - cl. 2 oblong leaf maple
Asian, evergreen maple, handsome and graceful, quickly growing to a rounded, 30 ft tree with leaves that are, in this form, very blue on the top side and strikingly silver underneath, creating a lovely shimmering quality. Best in north light or dappled shade -- out of western sun -- in rich, fertile soil with plentiful moisture. Tolerates temperatures to 10F or so, the bottom of USDA zone 8, but best in a protected spot out of wind to avoid leaf damage in the low teens F.
Sapindaceae $014 3D

Acer pentaphyllumasian maple
Deciduous and rare Chinese maple, with deeply cut, 5-lobed leaves - very un-maple-like and very graceful and charming, leafing out late in spring and showing off in autumn with bright colors. This delicate tree, nearly extinct in the wild, grows slowly, reaching perhaps 15 ft over a long time. A lovely addition to a garden of any size in sun to part shade and well-drained soil.

Actinidiaceae $015 4D

Actinidia pilosula variegated kiwi
Stunning and rarely seen kiwi with long narrow leaves with white tips that contrast brilliantly with the basic green foliage, the coloration appearing and/or becoming more pronounced on mature vines. A deciduous vine, to 15-20 ft, with unusual flowers, clusters of pink blossoms, in spring. Originally from East Asia, these are vigorous growers, best with support in full sun to dappled shade or even full shade. Give them rich soil, moist and well-drained. Frost hardy in USDA zone 6.
Actinidiaceae $014 4D

Aeschynanthus sp. NAPE 008
This diminutive, unidentified species was collected in southern China and grows only 4-6" tall with a spread of about 18”. As is typical of the gesneriad family, these can be epiphytic on wood or damp scree or indeed can live on a windowsill with fertile soil. The crisp, light green and compact foliage makes a pleasing background for the 2”, fiery orange, trumpet flowers. We have found it most beautiful in a tall pot with the foliage tailing over the side. A superb woodland plant in mild places, these have so far tested frost hardy only to the bottom of USDA zone 9.
Gesneriaceae $011 4D

Agapanthus 'Hinag'lily of the nile
A Japanese cultivar introduced by Barry Yinger, also known as A. 'Summer Gold'. With its lovely strap-like, variegated leaves, pale yellow with green centers, this agapanthus is as handsome out of flower as in. Summer to autumn flowers are mid-bluish-purple, lovely against the pale leaves. Reaches 12-18" high and wide in sun to partial shade with summer water. Frost hardy in USDA zone 8, possibly colder with winter mulch. Does well in pots.

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. Plants are small, to only 1 ft to 18" tall, and slowly form clumps to expand their presence in full to part sun and lean, well-drained soil. Frost hardy, so fa,r 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/Asparagaceae $014 4in

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, develops 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/Asparagaceae $016 4in

Agave 'Kissho Kan'lucky crown century plant
Stunning blue-gray leaves edged in white make this symmetrical rosette an outstanding addition to any collection. Yellow leaf spines darken to reddish brown adding distinction. To 15” tall x 18” wide and slowly offsetting. Needs light, and well-drained soil. Frost hardy to 20F, USDA zone 9. Best in container protected from winter wet where temperatures drop into the teens F or sit in the low 20s.
Agavaceae/Asparagaceae $15 4in

Agave 'Royal Spine'
Handsome, small agave, to only 18” tall x 2 ft wide with a dense rosette of dark green leaves blushed white (giving rise to an alternative name, A. 'Green Steel’). A cross between A. macroacantha and A. victoriae-reginae, the first contributing a dark terminal spine, the second, the darkly chiseled, spineless, leaf edges. Sun, good drainage and little summer water. Frost hardy in USDA zone 9. Looks wonderful in containers.

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.

Agave 'Silver Surfer' silver surfer hardy century plant
From a 1992 seed collection (YD 45-83) introduced by Yucca Do Nursery from the mountains above Palmillo, Tamaulipas, Mexico. Probably a hybrid of A. scabra x A. americana ssp. protoamericana, this clone, selected by fellow agave geek Tony Avent, exhibits an almost bead-like, silvery cast on deep blue leaves. Sweeet! Sun and good drainage, of course. Expect at least 4 x 5 ft in climates not falling below 15F though has recovered quickly from below 10F, upper USDA zone 7.
Agavaceae/Asparagaceae $014 6in

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/Asparagaceae $014 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/Asparagaceae $018 6in

Agave americana 'Opal' opal century plant
A variegated agave from the larger group often just called Marginata’ or ‘Variegata,’ this one most pleasingly variegated in creamy yellow on upright, blue-green foliage with sharp spines. To 4-5 ft tall and wide. Shared with us by plantsman Tony Avent as having been hardy in coastal Virginia. Though it has been nuked in North Carolina below 10F with winter moisture, it does show promise as being one of the tougher of the americana group as a very similar plant has grown unharmed in Portland gardens for a number of years. We expect at least 15F, mid USDA zone 8, and possibly lower if winter dry. In any zone a striking pot or container plant. Sun, well-drained soil, and little summer water.
Agavaceae/Asparagaceae $014 4in

Agave americana 'Variegata'variegated american century plant
Striking plant with beautifully curved blue leaves, well toothed and edged in rich cream.

A plant in Brookings, OR measures 10 x 10 ft. after 10 years.
Agavaceae/Asparagaceae

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/Asparagaceae $014 2D

Agave bracteosa 'Calamar'solitary candelabrum agave
Selected by Pat McNeal, this is a non-clumping form of the species, still resembling a bromeliad with lax, spineless leaves that are, in this form, consistently blue-tinted. As with the species, polycarpic and rare in cultivation. Often found clinging to cliff sides, these plants love the cool summer nights of the Northwest. Half sun, well-drained soil, and only occasional summer water. Frost hardy to 10F, USDA zone 8.
Agavaceae/Asparagaceae $016 4D

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/Asparagaceae $024 6in

Agave chrysanthagoldenflower century plant
Sharp spines, on the margins of long and stiff, green leaves with a strong, particularly pointed one on the tapered leaf tip, mark this striking agave that blooms in early summer with tall candelabras of yellow buds opening to bright , golden-yellow flowers - very showy with a faint aroma of coconut. Found on dry, open slopes in Arizona, these can reach 3 ft tall x 5 ft wide as solitary rosettes, growing in full sun and well-drained soil with little or no summer water once established. Best grown away from high traffic areas where the spines could be dangerous. Flowers only once before dying and regrowing from basal offsets. Frost hardy to 17F, uppermost USDA zone 8.
Agavaceae/Asparagaceae $011 2in

Agave chrysantha 'Blue Streak'blue streak century plant
A new Cistus introduction. Found near the Barnhard Trail in central Arizona, where diversity among the species if common, this form had the unusual habit of sending out colonies of young plants, each a rather pale, jaw-dropping, almost celadon blue. Given the habitat and this plant's situation in a northern aspect, we expect tolerance for anything we throw at it and others of its ilk. To about 5 ft x 5 ft with narrow, banded leaves. Prefers decent drainage, as one would expect, and winter drought. Happy with fairly generous summer water to push it along. Frost hardy, we believe, to between 0 and 10F, USDA zone 7, and possibly tougher.
Agavaceae/Asparagaceae $014 4in

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/Asparagaceae $012 2D

Agave durangensis durango agave
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/Asparagaceae $015 4in

Agave felgeri mescalito
Named for friend and botanist, Richard Felger, and found by him as well inhabiting dry, stony hills of western Sonora, this rare, A. parviflora relative has more robust leaves and rosettes. Triangular, gray-green leaves adorned with white markings and abundant cobweb-like filifers form clumps of multiple rosettes to no more than 8" tall. Happy in garden situations if provided excellent drainage and a fine pot specimen as well. Frost hardy to between 15 and 20F, mid to upper USDA zone 8, the drier the better.
Agavaceae/Asparagaceae $014 4in

Agave ferdinandi-regis king ferdinand agave
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/Asparagaceae $016 4D

Agave funkiana
A handsome agave with a pale stripe down the center of the thick, pointed, green leaves edged in curled spines and tipped with a very sharp spine. Can reach up to 3 ft tall in clumps as wide. Easy, safe from foot traffic, in sun to part shade and well-drained soil with occasional summer water to speed growth. Frost hardy to 15F, mid USDA zone 8, especially if winter dry. Can also be grown in containers with winter protection.
Agavaceae/Asparagaceae $014 6in

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/Asparagaceae $016 6in

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/Asparagaceae $016 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/Asparagaceae $015 4D

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/Asparagaceae $014 4in

Agave gracilipes [Alamagordo, NM 5000 ft] slimfoot century plant
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/Asparagaceae $015 4D

Agave havardianahavard's century plant

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/Asparagaceae $016 4in

Agave neomexicanamescal
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.

Agave ocahuinerf® 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.

Agave ornithobromamaguey pajarito
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 summer moisture; winter drought decreases chance of problems. Full sun to dappled shade, in a bright window, or your nearest lava outcrop. We have had this in our garden, hardy for the last few years with luck. Should be protected below the mid 20s F, so best for mildest parts of the world or as fabulously small-scale container plants. Frost hardy in USDA zone 9.

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.

Agave ovatifolia 'Frosty Blue' whale's tongue century plant
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.

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.

Agave parrasanacabbage head agave
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.

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/Asparagaceae $015 4in

Agave parryi 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.

Agave parryi var. huachucensis
From, yes, the Huachuca Mountains in southern Arizona and into northern Sonora, this beautiful gray/blue century plant forms a classic 20-24” artichoke shape, eventually offsetting to form small colonies. From mid-elevation (5-7000 ft) this, though not the most frost hardy of the parryi clan, takes 10 to 15F in stride, mid to upper USDA zone 8 -- lower if very well drained. Full sun and summer water in Mediterranean areas.
Agavaceae/Asparagaceae $016 6in

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/Asparagaceae $014 4in

Agave parryi var. truncataartichoke agave
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.

Agave parviflora - Ruby, AZ smallflower century plant
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/Asparagaceae $016 6in

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/Asparagaceae $016 6in

Agave salmiana var. feroxgiant agave
Huge, scary agave, to 4-6 ft tall x 6-12 ft wide over time, with an urn-shaped silhouette made up of foot wide, gray leaves. Originating in Mexico, these are common as accents in gardens with Mediterranean climates, as they rarely flower. Sun, good drainage, and very little summer water is necessary. Cold hardy in USDA zone 9, to 20-25F. Good for containers.
Agavaceae/Asparagaceae $15 4D

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/Asparagaceae $016 6in

Agave schidigera 'Black Widow' black widow thread-leaf century plant
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/Asparagaceae $016 6in

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.

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/Asparagaceae $019 4D

Agave toumeyana - Fish Creek Hill, AZ bird food agave
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/Asparagaceae $014 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.

Agave triangularis triangle agave
Unusual agave, the 18-14" long, olive-green leaves, narrow and, indeed, triangular (dagger-shaped), with a paler mid section, small spines on the leaf margins, and an intimidating, 1", terminal spine, these stiff leaves radiating from central rosette in an open, starburst pattern. Not known for blooming. Found in Mexico in both Puebla and Oaxaca, with little rainfall or winter frost, these are best in sun to part shade and good drainage with little summer water once established. A wonderful garden plant -- where spines won't hurt wandering friends -- where temperatures don't drop below 25F, mid USDA zone 9.

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/Asparagaceae $014 4D

Agave utahensis ssp. kaibabensis SBHMPS 6747

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.

Agave victoriae-reginae 'Kazobana'gold-edged queen victoria agave
This special variegated century plant was introduced by Japan's Yoshimichi Harose and is a particularly lovely version of various gold-edged forms floating around horticulture world for some time. The rosettes grow to about 15" at maturity with lovely, golden brocade patterns on the leaves. The offsets made for a number of years should be coveted as valuable trading material. As gold variegated plants tend to be a bit more sensitive than their kin, best planted out of the most direct blast of the sun. Expected to be as frost hardy as the non-variegated forms, into upper USDA zone 8 with excellent drainage. Best tried in container first. We are currently offering young plants.

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.

Agave zebra zebra agave
From north central Mexico, this beautiful plant, with narrow leaves to 4 ft striped silver-blue and olive-green, makes a stunning pot or garden specimen. Though the plant does occasionally offset, offspring might be removed not only to propagate the plant but also to maintain the presence of an individual and solitary specimen. Best in full sun with excellent drainage. Not from as high elevation as some, A. zebra seems quite happy into the upper teens F, upper USDA zone 8, but can receive frost damage below. Winter drought or cover extends its hardiness lower.

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 $015 3D

Arctostaphylos manzanita 'Hood Mountain' hood mountain manzanita
This possible hybrid of Arctostaphylos canescens was introduced from Hood Mountain in Sonoma, California by Nevin Smith as an upright form, to 6-10 ft tall and wide, with dark purplish bark, gray-green leaves, and white flowers in later winter to early spring. Great early food for hummingbirds and butterflies. Best in lean soil and hot sun. Drought tolerant so no summer water is necessary once they are established. Easily frost hardy in USDA zone 7.
Ericaceae $015 3D

Arctostaphylos manzanita SBH 7630 - cl 1 manzanita
A vigorous clone with an upright form, rich green leaves, and flowers barely tinted pink. Another easy manzanita for the garden. To about 14-15 ft tall if pruned for its upright form, otherwise easily kept below 5 ft. The flowers appear from December through February; the molle covered fruit comes on in summer, a nice contrast to the leaves and a compliment to the rich cinnamon colored bark. One of the garden water tolerant species but still prefers well-drained soil and careful summer watering, especially in hot weather. Should be frost hardy to about 0F, USDA zone 7.
Ericaceae $015 3D

Arctostaphylos manzanita SBH 7652 manzanita
A Cistus introduction. Collected in the wild in northern Lake County, this especially robust plant reaches well over 15 ft in 5-8 years with soft green leaves tinted gray-blue and the palest of pink flowers from December to February, all offset by warm orange bark. Prefers summer drought though more tolerant of summer water than most. A wonderful small tree for the dry garden. Frost hardy in USDA zone 7.
Ericaceae $015 4in

Arctostaphylos myrtifolia SBH 7634lone manzanita
This plant, found growing with A. viscida, has slightly larger leaves than the species, to about 1/3", and possibly represents a hybrid. We do know it has not been as fussy in the garden as the species, though we still recommend the usual arctostaphylos conditions, soil low in organic material and very little water in summer or any time when temperatures are hot. A sweet, small plant, to about 2 ft tall x 3 ft wide with red stems and pearl-pink, late winter flowers. Perfect as a specimen or low hedge. Frost hardy to close to 0F, USDA zone 7.
Ericaceae $15 3D

Arctostaphylos silvicola SBH 7491 bonny doon manzanita

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 $015 4in

Arctostaphylos stanfordiana 'Red Rover' standord's manzanita
In California's southern Medecino County among golden grass and blue oak we found this pretty specimen all by itself, growing to 4-5 ft with upright stems and shiny bright green leaves contrasting with the red stems. White, midwinter flowers are barely blushed pink and last into early spring followed by orange-brown fruit that compliments the cinnamon colored bark. One of the more garden tolerant arctostaphylos provided decently drained soil, full sun to dappled shade, and no heavy-handed summer water, especially while temperatures are hot. Frost hardy to 0F, USDA zone 7.
Ericaceae $015 4in

Arctostaphylos viscida SBH 7632 sticky manzanita

Arisaema sp. JSM - Fan Xi Pan, Vietnamcobra lily
This collection from northern Vietnam by Joshua McCullough produces leaves of only about 18" in a pleasing spring-green. But more interesting are the late spring and summer, striped flowers with coloring nearly chocolate to yellow to light spring-green between the stripes. Shade, rich soil, and summer dampness are best, with good drainage for winter rains. Frost hardiness is as yet untested, but we assume at least USDA zone 8.

We once thought this species too tender for permanent planting in these parts, but they have thriven for many years now, giving us courage. Easy in average garden conditions, luscious with summer water. with bright green, iris-like leaves to 2 ft or a bit more, and clusters of sky-blue flowers from spring through fall -- all from the small inflorescence, so don't cut them back. Bright light is best. We find these most outstanding when planted with yellow foliage nearby. Evergreen to the upper teens F, upper USDA zone 8; regrowing, especially with mulch, from 10F or so. (Also known as Aristea capitata.)

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.
