Aeonium 'Cyclops'

Aeonium 'Cyclops'giant red aeonium
Reddish-bronze leaves with a green “eye” in the center are a standout on this large aeonium, to 4-5 ft tall and 3-4 ft wide. A cross between the darker A. ‘Zwartkop’ and the more wavy leaved A. undulatum, these succulents are cold hardy to 25F, USDA zone 9b, so best in pots or a very! protected area. Well-drained soil in sun or shade with little water for plants in the ground, a bit more in containers.
Crassulaceae

empty

Aeonium 'Jolly Green'
Jolly green indeed! A low-growing succulent that remains under 1 ft tall x 1-2 ft wide -- wider over time, with multiple green rosettes, each 8-10" wide. Pale, greenish yellow flowers cluster among the leaves in summer. Sun and well-drained soil is best with little water required in summer and almost none in winter. Frost hardy to 25F, USDA zone 9b, so, where temperatures drop lower, best in containers with winter protection.
Crassulaceae

Aeonium 'Strybing Red'

Aeonium 'Strybing Red'
Another sedum relative, this with 4" rosettes of slightly toothed leaves that turn deep red in winter or in bright light. Forms clumps to 18" wide. Where temperatures don't drop below 25F and plants can be protected from freezing, these are fine in the garden. Otherwise best in pots that winter indoors or in a very! protected garden area. Well-drained soil in sun or shade with little water for plants in the ground, a bit more in containers. Frost hardy to 25F, mid USDA zone 9.
Crassulaceae

Aeonium 'Zwartkop'

Aeonium 'Zwartkop'
Very popular, shrub forming, sedum relative from the Canary Islands with rosettes of nearly black leaves on gray-brown stems rising to 3-4 ft. Yellow, star-shaped flowers appear in clusters in late winter and early spring on mature plants. For sunny coastal areas or part shade inland with occasional but deep summer water. Frost hardy to the mid 20s F, mid USDA zone 9, and a superb container plant to bring inside to a bright spot where temperatures drop lower. Also found as A. arboreum 'Zwartkop' and occasionally as A. manriqueorum 'Schwartzkopf'.
Crassulaceae

empty

Aeonium arboreum 'Variegatum'
This sedum relative has a branching growth habit producing compact, variegated, succulent rosettes to approximately 12" tall. Prefers full to part sun, well-drained soil, and occasional water, especially during the growing season. Excellent as a container plant that can be brought inside if temperatures fall below the upper 20’s F. Frost hardy to mid USDA zone 9.
Crassulaceae

Aeonium canariense

Aeonium canariensecanary island aeonium
Another wonderful succulent for the gardener’s palette. Growing up to 3 ft tall and wide, this rosette-forming plant does very well in the garden where temperatures don't drop below 25F, mid USDA zone 9, and plants are protected from freezing. Otherwise, best in pots or as a temporary garden display. Does best in sun with sheltering from hottest afternoon rays and a bit of summer water now and again. Too cool!
Crassulaceae

empty

Aeonium canariense var. virgineum velvet rose
From the Canary Islands, this virgin aeonium probably won't flower for you, but its pale green, aromatic rosettes of fuzzy, 8" leaves are very satisfying. Full to part sun with occasional summer water. Frost hardy to about 20F or so, the bottom of USDA zone 9, so best used as a container plant where temperatures are harsher and kept indoors in a bright but cool place with occasional water in winter.
Crassulaceae

empty

Aeonium domesticum 'Variegatum'
Compact evergreen succulent with loosely held rosettes on short stems, the succulent green leaves variegated in creamy white to yellow. Bright yellow flowers appear in summer. To only 12" tall. Prefers well-drained and lean soil and, during the winter growing season, bright light and regular water. In summer keep cool and shaded with occasional careful water. Frost hardy in USDA zone 9b; protect below 30F. Cheeerful container plant.
Crassulaceae

Aeonium haworthii

Aeonium haworthiipinwheel
Open rosettes, to 3-4" wide, of bluish green leaves with red edges top this multi-branched shrub from the Canary Islands. To up to 2 ft tall and wide, with late spring flowers of pale yellow to white that rise above the foliage. Full sun to light shade on the coast or light to full shade inland. Prefers well-drained soil and little to no summer water. Frost hardy to 20F, USDA zone 9 so, where winter temperatures are colder, best in a pot with winter protection.
Crassulaceae

empty

Aeonium undulatum
Stems to 3 ft tall hold rosettes 8” across with bright green leaves that ...yes...undulate on the edges. Yellow flowers emerge from the center of the rosette. Sun to part shade with normal water. Only frost hardy to USDA zone 9, so best in pots that can be protected when temperatures drop below freezing.
Crassulaceae

Agave 'Blue Glow'

Agave 'Blue Glow'
Handsome, small agave, its stiff leaves -- to 1-1.5" wide and blue-green with red margins edged in yellow and a red terminal spine -- are particularly lovely when backlit. Plants are small, only 1-2 ft tall and wide at maturity. This hybrid between A. ocahui and A. attenuata was created by Kelly Griffin. It is solitary, enjoying full sun, good drainage, and little summer water. Frost hardy to at least 15F, mid USDA zone 8, with good drainage, of course, and possibly lower.
Agavaceae/Asparagaceae

Agave 'Burnt Burgundy'

Agave 'Burnt Burgundy'century plant
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 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/Asparagaceae

Agave 'Kissho Kan'

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

Agave 'Ruth Bancroft'

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/Asparagaceae

empty

Agave aff. macroculmis T73-99
These, from the mountains of Tamaulipas in Nuevo Leon, Mexico at 7120 ft, are almost undoubtably a stable hybrid between A. montana or possibly A. gentryi - both high mountain dwellers - and A. scabra as it sneaks up toward the passes. Light-blue leaves, deeply dentate, form rosettes to 3ft. Tolerates moderate shade if well drained, otherwise full sun. Frost hardy to 15F, mid USDA zone 8, possibly below 10F if kept dry in winter.
Agavaceae/Asparagaceae

empty

Agave americana 'Cornelius'
Miniature form of the monstrous century plant, forming rosettes to under 2 ft, each leaf centered green with pleasing cream to gold leaf margins. In stunted form gives whole plant the appearance of a star. Frost hardy to upper USDA zone 8 or a bit colder if dry and under an the eaves or another protected spot in winter. Either way a fabulous pot plant. Full sun.
Agavaceae/Asparagaceae

Agave americana 'Mediopicta 'Dwarf Alba''

Agave americana 'Mediopicta 'Dwarf Alba''dwarf 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

empty

Agave americana 'No-Po'

Agavaceae/Asparagaceae

Agave americana 'Opal'

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

Agave bracteosa

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

Agave funkiana 'Blue Haze'

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

Agave funkiana 'Fatal Attraction'

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 if kept dry in winter. Does well in containers.
Agavaceae/Asparagaceae

Agave geminiflora

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

Agave gentryi 'Jaws'

Agave gentryi 'Jaws'hardy century plant
From an intriguing group in an intriguing and floristically rich part of the world, northeastern Mexico's Sierra La Peña, where three agaves inhabit the upper slopes from 8-9,000 ft, this one now accepted as the species A. gentryi. This selection, made by the Yucca Do boys in the early 1990s, has beautiful gray-green rosettes of sharply pointed leaves with deeply indented leaf margins, double, reddish teeth, and embossed impressions of the older leaves on emerging new growth. Has been very slow to offset. To about 24-36" tall, this selection, found amid pines and oaks in light shade on rubbly limestone outcrops, accepts a myriad of garden conditions but resents wet leaves sitting in the crown. So far, unharmed in upper USDA zone 7 winters.
Agavaceae/Asparagaceae

empty

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

Agave gracilipes

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

Agave havardiana

Agave havardianahavard's century plant
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/Asparagaceae

empty

Agave kerchovei
For the masochists among us, this most intriguing indeed. Extremely sharp and jagged century plant, a narrow endemic of warm southern Mexico look more like a great white shark's tooth than a plant. The blue-green leaves are edged and spined in white. Growing 2 to 3 feet high and wide in full sun. Alas, only frost hardy into the upper 20s, USDA zone 9.9. Best in container protected from winter wet. Fabulous container plant, nowhere near helium balloons.
Agavaceae/Asparagaceae

Agave neomexicana

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; tolerating temperatures to -20F, USDA zone 5, with good drainage.
Agavaceae/Asparagaceae

Agave ocahui

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.
Agavaceae/Asparagaceae

Agave ornithobroma

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.
Agavaceae/Asparagaceae

Agave ovatifolia

Agave ovatifoliawhale'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 pinyon/juniper/oak country above 8000 ft, the exceedingly wide, beautifully toothed and chalky blue rosettes 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/Asparagaceae

empty

Agave ovatifolia 'Frosty Blue' whale's tongue agave
A Cistus introduction. 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 classically shaped leaves, cupped, upright, and slightly outward bending. 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/Asparagaceae

Agave parryi var. huachucensis

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

empty

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. Full sun in lean, well-drained soil with occasional summer water in dry climates. 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.
Agavaceae/Asparagaceae

Agave parviflora ssp. flexiflora

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

Agave salmiana var. ferox

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

Agave shrevei 'Gigantea-Dentata'

Agavaceae/Asparagaceae

empty

Agave striata - Espadina form
Found in the wilds of northern Mexico, a symmetric plant that clumped in what appeared to be piles of tumbleweeds from a distance. Grows to about 18” x 18” with leaves tinted blue, often tipped purple-pink in full sun. Water sensitive - needs great drainage. Hardy into the upper teens. Sun. Cold hardy to 16F, mid USDA zone 8.
Agavaceae/Asparagaceae

Agave toumeyana var. bella

Agave toumeyana var. bellatoumey's century plant
A rare and unusual plant with particularly dense rosettes of narrow, dark green leaves with striking white markings and decorative filifers, or threads, as an added attraction. Extremely compact, each rosette maturing to around 8-9" in diameter. 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/Asparagaceae

Agave victoriae-reginae

Agave victoriae-reginae
Beautiful agave from N. Mexico. Olive-green rosette of blunt black-spined leaves marked with wide silvery white striations. Slow growing to 18” tall and wide, offsetting slowly. Rated to 12F , bottom of USDA zone 8; has survived in dry winter places, e.g. Denver, CO, to well below 0F, USDA zone 7 and below. A beautiful pot specimen.
Agavaceae/Asparagaceae

Agave victoriae-reginae 'Porcupine'

Agave victoriae-reginae 'Porcupine'porcupine queen victoria agave
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/Asparagaceae

Agave weberi 'Arizona Star'

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

Agave x leopoldii

Agave x leopoldii
Compact and architectural century plant, a hybrid cross of A. filifera and A. schidigera 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. Offsets eventually. A most attractive, small container plant, rarely growing more than 18” x 24", and a great addition to the dry or rock garden in a sunny site with gritty soil. Frost hardy in USDA zone 8b, to 15F or so and as low as 10F if protected from overhead moisture.
Agavaceae/Asparagaceae

Aloe 'Brass Hat'

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

empty

Aloe 'Latte'
Very nice, small aloe hybrid, the rough textured leaves opening green with brown spots and maturing to overall brown with hits of green. To 2-4" tall x 6" wide. Best in well drained soil in full to part sun. Frost hardy only to 25F, mid USDA zone 9, so best kept in containers to be moved indoors in winter and allowed to dry a bit before watering. Both heat and drought tolerant in the ground. A nice addition to the succulent collection outdoors or in.

Beschorneria aff. yuccoides ssp. dekosteriana - 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. (Originally sold as Beschorneria aff. decosteriana - large green; the name now conforming to accepted taxonomy.)

Carnegiea gigantea saguaro cactus
Surprise! These really are the famed saguaro cactus, iconic plant of the southwest, a very young version to be sure with their round bodies and giganto white thorns. But they grow up, very slowly, eventually forming thick stems with 2" thorns on the ribs, and often producing branches that curve upward. Frost hardy to 20F, USDA zone 9, so think of pot culture.
Cactaceae

Cistanthe grandiflora 'Bill Teague'

Cistanthe grandiflora 'Bill Teague'
Another form of C. grandiflora, the rosettes of blue-green leaves much bluer in this form given to us and named by Bart O'Brien's from garden in Pomona, California.

Best in sun and well-drained soil with little water required. Frost hardy into the mid 20s F, USDA zone 9b for outdoor planting, and a superb "temperennial" or container plant to winter indoors where temperatures dip lower.
Portulacaceae

Cotyledon orbiculata

Cotyledon orbiculatapig's Ear
A classic succulent with huge rounded blue-gray leaves and bright orange and yellow flowers held on foot high spikes in summer. Easy and fun in containers, and much hardier than they might appear, surviving into the mid teens if kept dry. Full sun to part shade. Hardy to 15F. USDA zone 8b.
Crassulaceae

Crassula arborescens

Crassula arborescenssilver dollar plant
Striking, red-edged, silver-blue-gray leaves, to 3" long, cluster on thick and fleshy, branching stems to 3 ft tall and possibly taller on this outstanding succulent from South Africa.

Dasylirion texanum

Dasylirion texanumtexas sotol
As the name would imply, this gem of a garden plant is native to west and southern Texas into Mexico and is one of the hardiest of the lot. Deep green rosettes, with small backward pointing spines and attractive golden filifers at the ends of the leaves, eventually form small trunks but are attractive as focal points or repeated rosettes in the garden. As denizens of the southern Great Plains, they love a thunderstorm or two in the summer and don't mind being dry in the winter, though they are tolerant of moisture. Sun to dappled shade, the main problem with dappled shade being dead leaves, not fun to pull out of the center of the plant -- your arm could get stuck that way, as my dad used to say about forbidden things. Reports tell us of frost tolerance up to -20F, USDA zone 5. Wow! Also great container plants.
Liliaceae

Dasylirion wheeleri

Dasylirion wheeleriblue sotol, desert spoon
The best known and one of the more spectacular of the genus, these trunk-forming denizens of southeast Arizona to southern New Mexico and south into Sonora can grow as tall as 8 ft with 4-5 ft rosettes of very pretty gray-blue, adorned with small golden teeth and threadlike filifers at the leaf ends. Beautiful when back lit. Not fussy about water or soil though would rather not sit in winter wet. Great container specimens. This high elevation collection from southeastern Arizona should be frost hardy into the 0 to 10F range, USDA zone 7, especially in bright light with good air circulation and very well-drained soil. Said to be deer resistant.

Bromeliaceae

Dyckia 'Red Devil'

Dyckia 'Red Devil'red-leafed dyckia
This, one of the most colorful Dyckia in our collection and a probable hybrid between D. platyphylla and D. leptostachya, grows to 10-15" high and 18" or so wide in reasonable time with elegantly spined rosettes of deep olive green, burnished intense red, more so with more light. Spring and summer flowers are of burnt orange atop 2 ft stalks. One surprise is the reported frost hardiness, with some testimonials to 8F though we'd be a bit skittish there; we're more confident in the mid teens briefly, mid USDA zone 8, probably colder if dry. Fine container plant, a bit slow growing and offsetting so will remain within bounds for some time.
Bromeliaceae

Dyckia choristaminea

Dyckia choristaminea
Terrestrial bromeliad with succulent, spidery leaves mottled deep purple and forming rosettes to only about 4.” Flowers are produced in summertime clusters of orangey red. Offsets quickly after flowering. Full sun for best color. We find it best as a pot specimen though would make a good wall or rock garden plant where temperatures seldom drop to 18F, upper USDA zone 8.
Bromeliaceae

Dyckia leptostachya

Dyckia leptostachya
This Brazilian native succulent, to 1 ft tall and wide, has blushed red leaves and is often used in hybridizing to add color to new cultivars.

Faucaria sp.
Unidentified faucaria, probably Faucaria felina, the largest species, but nevertheless lovely with it's yellow flowers opening around noon and closing in the afternoon -- as long as they have sun. Succulent leaves are triangular and toothed along the edges (hence the common name of "tiger jaws", held in crowded rosettes. Best with good drainage and lots of light -- a bit of shade where sun is very hot. They enjoy regular water in spring and fall, their growing season and should be kept moderately dry in winter and summer. Not frost hardy in Pacific Northwest winters, but as a USDA zone 9 plant, happy in pots.

Exceedingly drought tolerant but a little summer water would increase its growth rate. Sun to dappled shade. Frost hardy to about 0F, USDA zone 7, or even a little below.
Agavaceae

Opuntia 'Achy Breaky'

Opuntia 'Achy Breaky'
This complex undoubtedly three way hybrid (O. polyacantha x O. erinaceae v. columbiana x O. fragilis) from the mountains of eastern Oregon (where everyone know things get a little wild) grows only to 6" or so in height and about 3 ft wide, sporting white rust and deep brown spines along with chartreuse and yellow, late spring flowers, and provides interest in both texture and compactness. As is true for one of its parents, O. fragilis, the pads easily detach and connect to anyone or thing walking by. Good for sharing with friends; not so great in regions prone to violent shaking. Cactus requirements -- lean soil, good drainage, and little to no summer water. Frost hardy in USDA zone 4.
Cactaceae

Opuntia 'Baby Rita'

Opuntia 'Baby Rita'baby rita prickly pear
One of the most beautifully colored forms of the frost hardy cacti, a compact prickly pear to 2 ft, with pads to 3-4" that emerge blue-green often aging to greenish yellow tinted pink -- in this case a natural occurrence that doesn't indicate a lack of fertilizer. Late spring, ruffled flowers add to the palette. A hybrid cross between O. santa-rita and O. basilaris, this has all the charm of O. santa-rita in a much smaller plant. Full sun with sharp drainage. Frost hardy to -10F, USDA zone 6. Great in containers.

Opuntia 'Candelaria Flame'

Opuntia 'Candelaria Flame'
A Cistus introduction, from a most variable population in south central Nevada where these shaggy creatures can vary from gold to white to silver to red. Named for both the nearby small town and the color of its sign, this form of Opuntia erinacea var. ursina 'Candelaria' stood out after an October rain with its brilliant auburn spines exquisitely back-lit in the autumn sun. Slow to reproduce, adding only a pad or two at a time. These enjoy sharp drainage in full sun avoiding overly saturated winter soil. A very long lasting pot specimen. Frost hardy to -10F, USDA zone 5.

Opuntia 'Cyclops'

Opuntia 'Cyclops'cyclops prickly pear
Though the name has been around a long time, this plant's origins are unclear We do know this is a cute little prickly pear to 1 ft or 18" in height, probably having O. macrorhiza in its ancestry, with rounded pads of 4-6" forming tight clusters with dark bunches of spines appearing as polka dots from a distance. Cheery yellow flowers appear in mid to late spring. Good for container or sunny garden. And, as one would expect, very drought tolerant though west of the Sierra or Cascades would like a drink from the hose once in a while to spur growth. Frost hardy to -30F, USDA zone 4.

Opuntia 'Golden Globe' prickly pear
A Cistus introduction. From one of our favorite cactus habitats not far north of the aptly named Cactus Mountain Oregon, we believe actually named for particularly large specimens of pediocactus growing on its flanks. This selection from an obviously hybrid colony (parents = Opuntia polyacantha x erinacea var. columbiana) has shaggy upright pads to about 5" creating clumps 8-10" high by 3-4 ft wide with densely petalled flowers of undulating gold yellow, the orange stamens combining to create quite a show. Careful drainage is a must with these cliff dwellers and full sun. More summer drought tolerant than other prickly pears. Probably frost hardy to -30F, USDA zone 4.

Opuntia 'Red Gem'

Opuntia 'Red Gem'prickly pear
A gorgeous little prickly pear given to us by Colorado's Kelly Grummons and we could find no better description than this with hopefully enough credit due: "An apparent hybrid between O. basilaris or O. aurea with O. fragilis! To 4" high x 18" wide, with small, round, 2-3" wide pads that have very short spines and are fragile (pads break off easily). The petite, deep pinkish red flowers in June are abundant. Beautiful in the rock garden or in containers. Fergusen thinks this MAY be Opuntia polyacantha v. schweriniana … still a mystery." Frost hardy to -30, USDA Zone 4.

A Cistus introduction from the vicinity of Mormon Rock in southern California. This tightly clumping small form of beavertail has conical blue pads somewhat more flattened than the typical subspecies indicating a possible hybrid. Whatever the botanical case, each pad is only about 3" wide with well-spaced, bright orange glochids giving the whole plant a very cheery appearance. Nice medium-to-cherry-pink flowers appears in mid spring. Not minding extra winter moisture, these are a bit easier to grow than other beavertails, enjoying full sun. Excellent pot or rock garden plant and frost hardy to -10F, USDA zone 5, probably zone 4.

Opuntia basilaris var. heilii - Type local beavertail cactus
Named for botanist Ken Heil and collected from the northeastern population of the beavertail cactus. This clone, found growing in heavy alkaline soil in south central Utah and collected via a single pad years ago by plantsman Tim Hannis, produces dense clusters of blue-bodied plants, rather short on glochids, a good thing! It has been our favorite so far growing robustly and producing abundant, warm pink flowers in late spring. Easy in in the ground or container provided full sun and good drainage. Frost hardy to at least -30F, USDA zone 4.

Opuntia basilaris var. ramosa beavertail cactus
This far western Mohavian form of one of our favorite beavertails was found many years ago -- possibly an intermediate between the typical brachyclada form. Unfortunately collectors wiped out the colony seemingly within seconds of its discovery. Though we weren't among the collectors, propagules did get around, so here it is -- a pretty thing with each pad under 3", each one stepped atop another and each clump to about 18" tall. Good in containers or in the dry garden. Frost hardy in USDA zone 5.

Opuntia polyacantha 'Imnaha Blue'

Opuntia polyacantha 'Imnaha Blue'
A Cistus introduction. A common native of western dry lands, this clone, from northeastern Oregon's Imnaha Canyon, was found weeping several feet off a cliff of red ryolite, the nearly spineless, gray-blue pads appearing almost as if hanging in chains. Assuming not everyone has a cliff, these will form spreading mats to 4-12" tall and up to several feet wide. Early summer flowers are a warm, soft yellow. Ordinary cactus requirements -- sun, lean and well-drained soil, and little or no summer water. Undoubtedly frost hardy into USDA zone 4.

Yucca faxoniana

Yucca faxoniana
It has been long thought that many of the tree yuccas of northern Mexico are not frost hardy, but recently many of us rosette-fanciers have discovered their toughness. Yucca faxoniana produces 3-4 ft rosettes of stiff, emerald-green leaves with symmetric, pearly cream to brown filifers adorning each leaf. Quick to form full sized rosettes; slow to build a trunk that eventually reaches to 16 ft or more; and slow to branch. Fastest when given plenty of root room, free draining soil, and some supplemental water in very dry summer places. Excellent container plants. Prefer bright light. Frost hardy in USDA zone 7 with some success in warm zone 6 with excellent drainage and protection from freezing winds.

Yucca linearifolia
One of the most beautiful yucca species, related to Y. rostrata. The 3 ft rosettes atop an eventual 3-8 ft trunk resemble the Australian grass trees, xanthorroea, or a dim version of Dasylirion quadrangularis. Leaves are flattened and somewhat triangular, spring-green to nearly turquoise, and flowers are white on stalks to 3 ft or so above the foliage. Full sun to part shade with good drainage and lean soil. Best with occasional summer water. Found in a few scattered localities, these are from north of Galleana, NL, Mexico, in a most diverse habitat. Though the southern habitat would suggest little frost tolerance, these have so far withstood 5F, mid USDA zone 7.

Yucca periculosa

Yucca periculosa
From semi-arid slopes at mid to high elevations in southern Mexico, this small tree, to 20 ft or so and eventually branching, forms multiple rosettes of blue-green leaves, with evenly spaced, small filifers and outward facing flowers. For sun, lean soil, and dry places but enjoys an occasional summer thunderstorm. Has been unusually tolerant of frost for its southern latitude habitat, being reliable to about 20F, USDA zone 9, and a bit lower if winter dry. Otherwise a particularly nice container plant for many years, appearing like bonsai with its swollen caudex of a trunk.

Yucca recurvifolia
Large scale species, native to coastal areas of the Southeast and often used in Victorian days in our Portland neighborhoods and elsewhere in warmer parts of the country. Pretty much no-fuss plants and one of the boldest species for colder climates if provided reasonable water in summer in drier places. Each plant can grow from 4-5 ft with 3" wide, weeping leaves of glossy green tinted blue and 4 ft spikes of white flowers, most often in June but possible year round. As the plants form small trunks, some offsetting or branching occurs. Spectacular in containers or in the ground. Reliable in USDA 7; has found success in zone 6.

Yucca rostrata - specimen
These lovely creatures were grown from seed (NOT wild collected!). Many of these over 20 years old and hand selected for form and blue color. They have been potted this year and might or might not have begun producing this season’s roots -- if not, no fear, they will soon. All enjoy bright light with decent air circulation and all but the most swampy of garden conditions - so very easy care. Frost hardy to USDA zone 6 and have even resisted lower temperatures than that, but don’t push it. Water occasionally in summer west of the Sierra Cascades.

Yucca rostrata 'Sapphire Skies'

Yucca rostrata 'Sapphire Skies'
A Cistus introduction. Although Yucca rostrata is one of the most gorgeous species available, and definitely one of our top 500 favorite plants, it is exceedingly slow to reproduce from offsets, seed is difficult to come by, and seedlings vary as to their...blue-osity. Yucca rostrata 'Sapphire Skies' is a selection from one of our collections in the early 90s in northern Mexico, out of a seed batch of stunning blue-leaved plants. Through the magic of tissue culture, we now have a reliable source. These vigorous young plants quickly form a 3 ft, multi-leaved rosette of nearly jade-blue, forming 3 to 4 ft plants in 7 or 8 years under good conditions, eventually to 10 ft or more. Excellent container plants, providing fine architecture, or repeated in the dry garden and looking of dusty blue fireworks from a distance. Particularly beautiful reflected in late afternoon/evening light. Full sun to dappled shade. Not particular about soil, excepting standing water. Some supplemental irrigation in dry summer places. Frost hardy in USDA zone 6 and has been successful in zones 5 including the Denver Botanic Garden (Really!).

Yucca schottii 'Chiricahua High' schott's yucca, mountain yucca
A Cistus Introduction, our collection from near the summit of the Chiricahua Mts., a hardy yucca with very blue-gray leaves, to 3 ft long and sharply pointed, both stiff and more flexible than other "tree" yuccas. Eventually to 10 ft tall, single-trunked in youth to about 6 ft tall x 4 ft wide, then multi-trunked. Early summer flowers are white on tall stalks. For sun to part shade. An excellent garden species, both very drought tolerant and very frost hardy, accepting temperatures to -10F, USDA zone 6.

Yucca sp. [Tehuacana, Mexico]
A most handsome, trunk-forming yucca from the Mexican state of Puebla, to an eventual 8-10 ft -- possibly more, but none of us will live that long. Narrow, blue-green leaves in abundance make a beautiful and most architectural rosette even before lift-off. Flowers are white tinted rose-pink on slightly leaning towers. Sun, lean soil, and some summer water to boost growth. Frost hardy to 10 to 15 F, low to mid USDA zone 8 if winter dry; otherwise protect below 15F. Fabulous container plant. (Previously sold as Yucca tehuacana, the name under which is was received, we have now substituted a more proper nomenclature.)

Yucca treculeana
Tall yucca, its trunk reaching to 12 ft with stiff bayonet-shaped leaves, to 2” wide and 3 ft long, arranged evenly around the thick trunk. Spectacular by itself but when it grows up, in say 4 to 5 years, a giant flower stalk appears adorned with white flowers. Stunning! Originating in the southwestern United States and in Mexico, these are frost hardy to USDA zone 7.
