Quercus hypoleucoidessilver oak
We first fell in love with this plant in the 1980s upon seeing a collection from an expedition of Boyd Kline and Frank Callahan to northeastern Mexico. Our first up close and personal experience was on New Year's Day, seeing these exquisite 25 ft tall by 15 ft wide trees in the Chiricahua Mountains of southeast Arizona where, under bright blue skies and with a few inches of snow on the ground, the dazzling sliver undersides of the leaves reflected as if illuminated by spot light. Fast growing when young. The narrow leaves are very leathery and shiny and can age to maroon on the upper surface in cold temperatures. A plant for sun, well-drained soil, and quite possibly hardy into low to mid USDA zone 6. But we are sure about zone 7. Our favorite oak, really.

Ribes 'Pink Pearl'pink currant
A Cistus introduction. Though this new cross should involve long story about an involved, Cistus hybridization program, in fact, this was a seedling in our garden ... for which we are happy to take credit. And yes, it's possible the world doesn't need another Ribes sanguineum cultivar, but this one's different ... with dense, hanging clusters of late winter flowers that open white and fade to a warm pink. Flowers very well and we believe represents a color combination not in the trade. Typical western native plant care is required in lean soil and dappled shade -- though for this one full sun can't hurt --. with summer water to be applied sparingly and carefully only in cool weather. We expect frost hardiness to at least the bottom of USDA zone 7.

Grown for the foliage but flowers in summer with spikes of creamy flowers flushed pink. These mounding perennials, to 12-18" tall and spreading into 2 ft colonies, enjoy sun (with some water) to shade -- a ground cover that looks good in any conditions. Frost hardy to at least USDA zone 6.

Tigridia pavoniatiger flower
Beautiful irid widespread in Mexico, these high elevation collections produce 4” flowers of orange to dark yellow. Loves most garden conditions provided some summer water where dry. Will go happily winter dormant in the 20s F but resprouts again in spring, especially if mulched….even lower, to 10F, USDA zone 8, with more mulch… but there has to be a limit… Sun to dappled shade, spreading freely into attractive clumps. Good in containers.

Trachelospermum 'First Snow'asian star jasmine
A Japanese selection and one of a small group of cultivars with dark-reddish leaves, especially with bright light or in cool weather, with new growth softening to nearly florescent pink and peach and cream -- and polka-dotted in contrasting colors! The plant, when grown to a large clump, vine, or cascade, indeed, looks as if it has been lightly frosted with snow. Drought tolerant though much more vigorous with reliable summer water and an occasional application of nutrients. Sun to shade with well-drained soil, though willing to growing in nearly concrete. Has sweetly scented flowers but seldom so when planted as a ground cover; only when allowed to climb or mound and it reaches its summit will the flowers appear. Frost hardy in USDA zone 7.
Apocynaceae $012 4in

Trachelospermum asiaticum asian star jasmine
Given to us by plantsman Neil Bell, this small vine or groundcover has narrow, deep green leaves, with deep veins -- almost appearing variegated. A handsome and vigorous, star jasmine, easily reaching 6 ft in 2-3 years. Though shy to flower as a ground cover, climbing or container plants produce sweetly scented, creamy yellow flowers. Happy in sun or shade with regular summer water for best performance. Frost hardy to 0F, USDA zone 7.
Apocynaceae $011 4in

Trachelospermum asiaticum 'Chirimen' asian star jasmine
A glittering, tiny star jasmine, brought from Japan as a gift several years ago. It remained quite dwarf growing only an inch or two a year at first, gaining vigor as time went by. The 1/4" to 1/3" leaves are closely held, narrow, and streaked silver-white and dark green on dark stems. Each plant grows no more than 6" in height, mounding if in bright light or in tight quarters, becoming a miniature vine in dappled shade or if allowed to climb. After several years, "adult" leaves form, to 1/2", and small, sweetly scented, creamy flowers appear. It is hard to imagine a better small container, rock garden, or freestone wall plant especially when contrasted with darker colors. Full sun, for most compactness, to shade. Rich, freely draining soil. Frost hardy in USDA zone 8.
Apocynaceae $012 4in

Trachelospermum asiaticum 'Goshiki'asian star jasmine
Another wonderful star jasmine, an evergreen vine climbing or spreading on the ground to 6 ft, with leaves emerging pink and turning to cream and green. Fragrant yellow flowers add to the attraction on mature plants. Can be kept as a mounding shrub as well. Light shade is best with some summer water. Frost hardy to the mid teens F, USDA zone 8b.
Apocynaceae $012 4in

Trachelospermum asiaticum 'Hatsuyuki' asian star jasmine
An Asian star jasmine, very like our T. ‘First Snow’ (the English translation of ‘Hatsuyuki’) but slower growing and shrubbier, so kept separate in order to distinguish these different habits. As with T. 'First Snow' the leaves emerge pinkish white adding green then turning mostly green with age, creating a wonderful color texture in the garden. Sun to part shade with summer water. Frost hardy in USDA zone 7. Also useful as an indoor plant
Apocynaceae $015 4in

Trachelospermum asiaticum 'Kiifu Chirimen'asian star jasmine
Extremely congested Asian jasmine from the Miniature Plant Kingdom who used it mostly for bonsai & penjing work. It is a standout in the rock garden or in the open garden. Rarely flowering, its evergreen leaves are very handsome, especially with the slightly crinkled finish to them. Best in full to part sun with summer water. Frost hardy in USDA zone 7.
Apocynaceae $014 4in

Trachelospermum asiaticum 'Ogon Nishiki'asian star jasmine
Ever-colorful vine or scrambler keeps growing along the ground, over a bank or up a trellis or tree, showing off the yellow-orange-red-green marbled patterns of the evergreen leaves. We like the way the fresh new growth unfolds in the spring and the way the old growth colors in response to winter cold and hope you do too. Adaptable in sun to part shade with regular summer moisture for faster growth. Frost hardy to 0F, USDA zone 7.
Apocynaceae $14 4in

Trachelospermum asiaticum 'Ogon' asian star jasmine
Diminutive Asian jasmine, to only 2 ft wide by 6” tall -- can grow larger in time, with shiny gold leaves under 1" on orangey stems and, in spring, creamy, nearly yellow flowers. Wonderful for spilling over planters or as a small scale ground cover. Especially striking with black mondo grass, but isn’t everything? Does well with regular summer water in shade to full sun, though the colors can bleach in the brightest light. Frost hardy in USDA zone 8.
Apocynaceae $012 4in

Trachelospermum asiaticum 'Red Top'asian star jasmine
Hardy flowering jasmine, evergreen, to 10 ft tall or so, for trailing or climbing a wall. This one with deep, reddish bronze new growth is deep reddish bronze and dark bronze winter color. White flowers have a sweet and creamy fragrance. Sun to part shade with summer water. Frost hardy in USDA zone 7.
Apocynaceae $012 4in

Trachelospermum asiaticum 'Theta'asian star jasmine
A Cistus introduction, named for Sean’s mother, this extremely ornamental star jasmine has distinctve foliage -- very narrow, under 3/8" wide x 2" long -- and a vining, scrambling habit, draping beautifully over walls, in a rockery, or in a container. Vigorous and hardy in full to part sun with some summer water. Frost hardy in USDA zone 7.
Apocynaceae $012 2D

Trachelospermum asiaticum 'Variegatum' asian star jasmine
Given to us some years ago, origins unknown, this small vine or groundcover has narrow, deep green leaves, boldly splashed boldly creamy yellow -- one of the vigorous, variegated star jasmines, reaching 6 ft in 2-3 years. Though shy to flower as a ground cover, climbing or container plants produce sweetly scented, creamy yellow flowers. Happy in sun or shade with regular summer water for best performance. Frost hardy to 0F, USDA zone 7.
Apocynaceae $009 2D

Trachelospermum jasminoides - marbled long leafstar jasmine
This star jasmine with a rather dull name, brought from Japan just a few years ago, has leaves up to 4" x 1", marbled and streaked jade green, silver, and cream, blushing to a beautiful pink and maroon during the winter months. Not at all dull! It is also free flowering, especially when somewhat root bound in a container or grown in bright light,with large white flowers more sweetly scented than the...hint-of-electrical-fire fragrance of some star jasmine flowers. (You know you are a plant geek when you can walk amongst a star jasmine collection and tell them apart by their individual fragrances. We must get out more.) Full sun to full shade where it might make a beautiful contrast under darker leaved, broad-leaved evergreens. Reasonably fertile soil with regular summer water. A few nutrients never hurt. Frost hardy in upper USDA zone 7.
Apocynaceae $008 4in

Trachelospermum jasminoides 'Madison'star jasmine
A selection several years ago from Madison, Georgia where several species, some thought to be quite frost hardy were killed in a sub 0F freeze. This free flowering selection has 1 1/2" rounded leaves, quite felty on the reverse, and nearly 1/2" palest yellow flowers in great abundance in spring through early summer, then sporadically through fall. Makes a fine ground cover or pot specimen. One plant near our Portland home graces a 2 1/2 story chimney and is drop-dead gorgeous. Full sun to partial shade; at home in full shade but flowers more sparsely. Frost hardy in USDA zone 7, possibly even brief dips into upper zone 6.
Apocynaceae $014 4in

Trachelospermum jasminoides 'Mandianum'star jasmine
From Bob McCartney in Aiken, South Carolina comes this exceptionally durable, hardy star jasmine, to 10-12 ft, with shiny, leathery, dark green leaves and fragrant, creamy flowers at the yellow edge of the species’ variation. Regular summer water in full sun for most fragrant bloom. Frost hardy in USDA zone 7.
Apocynaceae $012 4D

Trachelospermum jasminoides 'Tricolor' star jasmine
Foliage is splashed with cream on this scandent evergreen vine. Typically T. jasminoides flowers, these creamy yellow, appear in summer, both lovely and fragrant. Lovely as a ground cover,scrambling over rocks or down slopes or climbing to 8-10 ft on any support. Provide full sun for best flowering along with regular summer water. Frost hardy in USDA zone 7.
Apocynaceae $012 3D

Trachelospermum jasminoides 'Variegatum'star jasmine
A pretty and delicate form brought from England in 1997, this cultivar is as vigorous as the species but the leaves, measuring about 1/2" x 2", are margined and streaked creamy white and plants show a great propensity for climbing. Sweetly scented flowers, more white than cream, in great abundance but small. Makes a wonderful contrast with other clinging vines with dark green leaves, e.g., creeping figs (Ficus pumila) or climbing evergreen hydrangeas (Hydrangea seamanii). We have used this in dark courtyards with such plants as variegated forms of Fatsia japonica and variegated aspidistra to great effect. Shade to sun, though not likely to flower in deepest shade. Fertile, well-watered soil preferably. Frost hardy in USDA zone 7.
Apocynaceae $014 4D

Trachelospermum jasminoides 'Wilsonii' star jasmine
Tough evergreen vine, willing to climb, scramble, or spread into a nicely textured groundcover of dark green leaves with prominent, silvery veins. Very glossy and even more striking in summer when sprinkled with sweetly fragrant, creamy white, star-shaped flowers. In autumn the foliage takes on red coloration from slight tints to a complete color change. Sun is best with some summer water. Frost hardy in USDA zone 8.
Apocynaceae $012 3D

Trachelospermum sp. - Cliff Parks star jasmine
Purchased years ago from the great nursery, Camellia Forest, this Cliff Parks collection, clearly related to T. jasminoides, has uniquely broad, triangular leaves with a slightly ruffled surface adding a particularly lovely texture in the garden or container. The flowers, creamy white with maybe a drop of yellow, have the typical star jasmine fragrance with a little drop of custard. We’ve enjoyed this plant for many years but have just now propagated it in enough numbers for you to enjoy as well. Drought tolerant, as are the other star jasmine, but prettier with some summer moisture. Sun or shade with best flowers in sun. Has taken USDA zone 7 winters in stride.
Apocynaceae $014 4D

Trachycarpus takil kumaon fan palm
A vigorous chusan palm with exceptionally large fronds, standing upwards of 4-5 ft and bending in a uniform manner giving the tree a robust and almost weeping effect. Quick growth, sometimes more than 18" of trunk per year in happy times. Best in sun, though quite elegant in dappled shade, in rich soil with summer water where dry. Frost hardy in USDA zone 7 though fans can tatter below 10F, regrowing in summer.
Arecaceae $012 4D

Trachycarpus wagnerianusjapanese temple palm
To us the most exquisite of the Trachycarpus clan, found nearly 200 years ago in a temple in southern Japan and known only from cultivation. The stiff, symmetric leaves, looking as if shorn carefully at the ends, are lightly edged in white indumentum and often have most attractive pale blue undersides. Because of the rigidity of the leaves, they never tatter in high winds. Their most unique feature and what makes them most easily recognized is the several years spent resembling a miniature palm, as from very early on their fronds become "adult" -- even when only 4" or 5" across. Can be kept dwarf for many years but in the ground, with adequate summer water, they grow even more quickly than typical chusan palms, actually doubling in size for several years. Our 10 year old plants are now approaching 12-15 ft in height. (A small tidbit: though an incorrect entry, a palm book years ago confused T. wagnerianus with T. takil when actually they have little in common.) Best in bright sun. About as frost hardy as T. fortunei but shows damage less easily, e.g. no tattering. Our seed is produced from our own isolated plants. Woohoo! These plants already at least 4 years old and producing adult fronds. Frost hardy to 0F, USDA zone 7.

Trichocereus chiloensis var. eburneus
Our collection of this black-spined cactus, found in the high mountains east of Santiago, Chile at the base of a ski resort. Reaching to 8-10 ft tall in their native habitat, these are handsome at any size with their cluster of black spines on top. Sun, of course. Occasional summer water speeds growth. Tolerant of winter wet if the soil is very well-drained. Provide protection where temperatures drop below 15F, mid USDA zone 8, or so. (Echinopsis chiloensis is a synonym.)

Tupistra chinensis 'Eco China Ruffles' chinese ruffles
An odd and primitive, evergreen, lily-family relative found by Don Jacobs on sacred Mt. Omei in China and introduced to horticulture rather recently. Actually, plants look neither odd nor primitive with their rosettes of 18" leaves, tall, narrow, light green and ruffled on the edges. A cheerful presence in light shade to very dark shade with summer water. Flowers are inconspicuous but produce orange berries. Cold hardy in USDA zone 7. (Also known as Campylandra chinensis 'Eco China Ruffles'.)

Myrtaceae $014 4D

Umbellularia californica - dwarf form [O'Brien Bog]dwarf oregon myrtle
A Cistus introduction. Dwarf Oregon myrtle (or dwarf California bay if living south of 42 degrees north). A normally stately tree in the avocado family inhabiting western Oregon and coastal California, these Siskiyou endemic forms reach only 6-8 ft as dense shrubs with evergreen leaves emerging bronze and aging to deep green. This clone becomes a dense, pyramidal form with leaves held upright displaying bluish undersides. A perfect chance to acquire this wonderful species in a manageable size. Small clusters of brush-like, yellow flowers produce shiny, green, nearly 1" “avocados” in autumn. Aromatic leaves can be used as seasoning (they are related to the Grecian Laurus nobilis). Should be an iconic shrub for the West Coast. Drought tolerant for sun or part shade. Frost hardy to -10F, USDA zone 6, at least.
Lauraceae $014 4D

Umbellularia californica [Fresno, CA] california laurel, oregon myrtle
Previously known as U. californica var. fresnensis and now included in the straight species, this form of the California bay laurel from Fresno, California has some distinctive features. A large growing, broad-leaved evergreen, these can reach to 30-40 ft or more, often with weeping foliage, the leathery leaves undercoated with soft, light-colored pubescence, making them particularly attractive and lighter in appearance than typical.Leaves are aromatic, as usual, and useful in cooking, a bit stronger than true bay leaves from Laurus nobilis. Small yellowish flowers are produced in spring followed by a round, green berry that matures purple. Full sun for the best pyramidal form, good drainage, and little summer water once established. Frost hardy to 0F, USDA zone 7.
Lauraceae $015 4D

Umbellularia californica SBH 7188 - dwarf formdwarf oregon myrtle

Umbellularia californica SBH 7204 - dwarf formdwarf oregon myrtle
A Cistus introduction. Dwarf Oregon myrtle (or dwarf California bay if living south of 42 degrees north). A normally stately tree in the avocado family inhabiting western Oregon and coastal California, these Siskiyou endemic forms reach only 6-8 ft and remain a tight gumdrop shape for may years. This is an opportunity to have this wonderful species and yet not have it be the only plant in your garden. Very good dense shrub, the evergreen leaves emerging bronze and aging to deep green. Small clusters of brush-like, yellow flowers produce shiny, green, nearly 1" “avocados” in autumn. Aromatic leaves can be used as seasoning (they are related to the Grecian Laurus nobilis).

Uncinia rubra 'Belindas Find' belinda's hook sedge
One of the bright, clumping sedges, this with bronze leaves variegated with striking. bright red coloration. Slow growing, to 12" tall x 15" wide and best used in the garden in combination with yellow or light green foliaged plants. For full sun to part shade with regular water in summer. Seed heads can get caught in fur -- both animal and people -- and are best removed. Frost hardy in USDA zone 8.
Cyperaceae $011 3D

Verbascum undulatum wavy leaf mullein
The gray-green and fuzzy leaves of V. undulatum do indeed undulate, their edges rolling and frilled, quite interesting and elegant in their first year, form a rosette close to the ground. It is in the second year that flower stalks rise up, to 1-3 ft tall, with sweet, yellow flowers along the stem -- producing seed to start the biennial cycle again. Having originated in Greece and the Balkans, these plants thrive in dry, inhospitable areas with full sun and little summer water. Interesting, unusual, and tough, they are frost hardy to -10F, USDA zone 6.
Scrophulariaceae $012 2D

Veronicastrum stenostachyum ssp. stenostachyum
Shared with us by plantsman Ted Stephens from an Asian excursion, this graceful, small vine, to about 6 ft with narrow, bronze-tinted, shiny, evergreen leaves, has late-season, small sprays of purple-blue flowers. For shade to partial sun; probably tolerant of full sun in damp climates. Certainly enjoys summer water. Perfect for places where wisteria just won’t fit or for accents in containers. Has been frost hardy to the bottom of USDA zone 8 and behaves as perennial in zone 7, quickly regrowing.
Plantaginaceae $014 4D

Viburnum aff. henryi
A particularly graceful shrub, larger in leaf and stature than the V. henryi that we have been growing for years, this with narrow and shiny leaves, to 5" or more, emerging with reddish coloration, maturing towards orange, and taking on a lovely sunset orange hue in frosty weather. White, late spring flowers look lovely against the evergreen foliage. This clone, shared with us by Scott McMahon several years ago, likes typical viburnum conditions -- shade to mostly sun with summer water in summer dry climates. Frost hardy to 0F, USDA zone 7.
Caprifoliaceae / Adoxaceae $014 3D

Viburnum foetidum var. quadrangularis
Handsome and rare evergreen viburnum from southern China. Burnished leaves emerge dark purple, turning a dark, shiny green upon maturity. Flowers appear in late spring in rounded clusters of white with purple anthers. Crimson fruit follows and last through the winter, good cheer for people and birds. A medium shrub, to 4-6 ft tall x 3-5 ft wide at maturity. Best in full to part sun with average summer water. Frost hardy in USDA zone 8.
Caprifoliaceae / Adoxaceae $016 4in

Viburnum harryanumsir harry veitch's viburnum
Diminutive species, to under 3-4 ft in five years, with arching branches and nearly round, spring-green leaves under 1/3". The flowers, in scale, are small and creamy white with small black berries late in season. At home in woodland gardens, but should be planted where large, falling leaves cannot smother it. Also at home in full sun and in containers with regular moisture and fertilization. Frost hardy in USDA zone 8; possibly upper USDA zone 7.
Caprifoliaceae / Adoxaceae $014 3D

Viburnum japonicum 'Variegatum'variegated wax leaf viburnum
Striking, evergreen shrub, to 6 ft tall x 5 ft wide, with yellow splash variegation on large, glossy green leaves. Early summer flowers clusters are white and fragrant, followed by red fruit that holds on into the winter. Still somewhat rare in cultivation. Part sun or high shade seems to suit it best with normal summer water. Cold hardy to USDA zone 7.
Caprifoliaceae / Adoxaceae $014 3D

Viburnum odoratissimum var. awabuki 'Chindo' sweet viburnum
Compact, upright form of this species, widely grown in gardens in eastern Asia though still not used to its full potential in warmer areas of our continent. This clone, brought from Chollipo Arboretum in Korea by the late J. C. Raulston, has grown to nearly 20 ft in some of our gardens but, indeed, is compact with a pyramidal form and branches that seldom splay. The evergreen leaves are mirror-shiny and deep apple-green tinted red, especially in winter. The flowers appear in flat cymes of white in spring and, by Halloween, have produced orange and black berries. Handsome small garden or street tree provided some summer water. Ideal as woodland tree or even in full sun in all but the hottest climates. Proven a bit hardier to frost than its nearest kin. Frost hardy in USDA zone 7.
Caprifoliaceae / Adoxaceae $014 4D

Viburnum oliganthum - white flowered form white flowered chinese viburnum
Shared with us by plantsman Ted Stevens after being obtained from a garden center in Japan. An upright shrub, to about 6 ft tall with thick, almost succulent evergreen, 3" leaves, and striking, hanging clusters of tubular, waxy flowers, white in this form, in spring and sometimes throughout summer. A rather new and interesting texture for woodland or full sun with occasional summer water. Frost hardy in USDA zone 7.
Caprifoliaceae / Adoxaceae $014 3D

Viburnum plicatum 'Cascade' doublefile viburnum
Large and handsome, deciduous shrub, to 10 ft tall and up to 12 ft wide, this cultivar somewhat smaller than the species, horizontally branched with dark green leaves. A striking structure alone, and magnificent with the long-lasting, white, lace-cap-like flowers, up to 4" across in late spring to early summer, and the red fruit that follows. Full sun to part shade with consistent summer water for best appearance. Tolerant of seaside conditions and said to be deer resistant. Frost hardy to -30F, USDA zone 4.
Caprifoliaceae / Adoxaceae $016 4D

Viburnum plicatum 'Ogon' golden doublefile viburnum
A dainty shrub, to about 6 ft with flattened, golden leaves of about 3” and charming cymes of white flowers in late spring. Orange-red fruits that arrive in late season add to the spectacle of florescent autumn color. We grow ours in dappled afternoon shade where it has been amazingly tolerant of direct sun. Requires summer water in dry places. Much slower growing than the species. Frost hardy in USDA zone 5.
Caprifoliaceae / Adoxaceae $014 4D

Viburnum propinquum chinese viburnum
Truly striking, evergreen viburnum from central and western China, to 6-8 ft tall x 4-6 ft wide, with shiny, dark green leaves on reddish stems. Late spring/early summer flowers are greenish white cymes followed by blue to black fruit in autumn. Average summer water in full to part sun; a bit of afternoon shade in hottest climates. Frost hardy in USDA zone 7. One of the best and a great substitute for the more common V. davidii.
Caprifoliaceae / Adoxaceae $012 3D

Viburnum tinus var. robusta
A large form of this useful evergreen shrub -- the identification having been deduced from the old, old Oregon plant from which it was collected, suggesting an eventual, gargantuan size of 20 ft or more with the typical leaves of V. tinus and the large clusters, to 4-5", of early spring, pink and white flowers followed by incredible blue fruit. Lots of space is suggested along with sun to shade with average water at least until established. Can be used as a screen or pruned into a small standard tree for the garden. Frost hardy in USDA Zone 8.
Caprifoliaceae / Adoxaceae $014 4D

Weigela 'Looymansii Aurea'
Glowing yellow foliage emerges in spring and gradually fades to spring green on this handsome, deciduous shrub, to 4-6 ft tall and as wide. Pink flowers brushed with purple appear in late spring and early summer adding yet more bright cheer. Bright light with protection from the hottest sun keeps the foliage fresh along with regular summer water. Frost hardy in USDA zone 5.
Diervillaceae $013 4D

x Fatshedera lizei 'Angyo Star'aralia ivy
One of the most beautiful selections of this popular plant form, a bi-generic cross between fatsia and hedera creating a vining shrub that is trouble free and useful as a low climber to 5 ft, a container plant, or ground cover. This cultivar, initially from Japan and shared with us by plantsman Ted Stephens, has 5-6",evergreen leaves of deep green with clearly defined, creamy white margins. Though it has been successful in exceedingly dark places, happiest in light shade with supplemental summer water where dry. Should be frost hardy into the single digits, lower USDA zone 7.
Araliaceae $016 4in

x Fatshedera lizei 'Curly'curly aralia ivy
This cross between ivy and fatsia is a winner in all respects. A viney shrub, non-clinging with somewhat lax stems that can reach 3 ft tall. This one has cute, curly leaves that add texture. Usually single stemmed, but branching can easily be encouraged by pinching the tips. As with others, it has been successful in exceedingly dark places, but prefers light shade with supplemental summer water where dry. Makes a fine houseplant. Frost hardy in USDA zone 8.
Araliaceae $012 4in

x Gordlinia grandiflora
A recent and long sought after cross between Franklinia alatamaha and Gordonia lasianthus by Dr. Tom Ranney at the North Carolina State University Station. Expected to be a lovely ornamental tree, to 15-20 ft tall x 12-18 ft wide, with shiny leaves of green with lovely red overtones, the red increasing in colder weather. Who wouldn't love a mostly evergreen tree that provides rich red fall color. Spring flowers are large, white, and showy. Easier than either of its parents in the garden in sun to part shade with regular summer water. Frost hardiness expected in USDA zone 7 if not 6.
Theaceae $022 4D

x Mangave ‘Bloodspot’
New and gorgeous, this hybrid between a unknown species of Agave and Manfreda has long, narrow, blue leaves liberally spotted in red with bright red teeth along the edges. Who wouldn’t want that? Rosettes are 1 ft tall x 14” wide and hardly ever offset. Sun and lean, well-drained soil. That much is known. Winter hardiness is not completely known yet, but hardy so far to 20 degrees, USDA zone 9. Great for a container while experiments continue.

Yucca aloifolia spanish bayonet
One of the larger hardy yucca, forming a trunk to 5-20 ft.... eventually. A great addition to the garden and fine in a container as well -- easy in both. Leaves are large, to 2 ft, sweeping, and sharply pointed. Mature plants produce spikes of white flowers tinged purple appear in early to mid summer. Full sun to half sun in well-drained soil. Easy. Frost hardy to 0F, USDA zone 7.
Agavaceae $014 4D

Yucca aloifolia 'Blue Boy'spanish bayonet
A plant Sean knew at the Berkeley Botanic garden, now sometimes sold as Y. aloifolia 'Purpurea', with somewhat soft, arching leaves that are green with purplish highlights in summer, turning more red in winter temperatures. Very tropical. To 4-6 ft. Sun to part sun and well-drained, lean soil with only occasional summer water once established. Frost hardy to 15 to 20F, mid USDA zone 8. An outstanding pot plant.
Agavaceae $015 4D

Yucca aloifolia 'Variegata' variegated spanish bayonet
A long coveted form of this sharp-pointed, spectacular tree yucca, native of the deep Southeast, the variegated forms have long been pass-around only plants because of their difficulty in reproduction. Now there's enough for everyone! 3 ft wide, stacked rosettes on branched trunks -- to 5-8 ft and more -- the creamy white variegations, tinting rosy pink in cold weather, make the plant's outline visible from quite a distance. Full sun to dappled shade providing leaves do not gather in the rosettes and cause rot. Well-drained soil. Supplemental water in dry summer places. Frost hardy in USDA zone 7.
Agavaceae $015 6in

Yucca angustissima 'South Side'narrowleaf yucca
A Cistus introduction. This diminutive relative of Y. elata occurs mostly north of the Colorado River in the area fondly regarded as the Arizona strip. Our collection, from the Hualumpai area, was found hanging from cliffs over the Grand Canyon creating a small “tree” to about 3 ft with compact, symmetric heads of leaves adorned with silver filifers. Eventually offsets forming a small colony. A beautiful plant for repetition or for container specimen. And a bit easier to grow than its larger cousin. Particularly beautiful where the sun can backlight the foliage. Drought tolerant though summer water can speed growth in dry areas. Frost hardy in USDA zone 5.
Agavaceae $018 4D

Yucca baccatabanana yucca
This trunk-forming yucca is a knockout in the landscape with curving trunks -- up to 10 per plant -- that snake out and stand up to 8 ft tall. Green leaves are stiff and decorated with longish filifers. Very architectural! In early summer, short flower stalks carry abundant white flowers. Full sun with excellent drainage, and, for best appearance, occasional summer water. Frost hardy to -20F, USDA zone 5 and possibly colder.
Agavaceae $015 4D

Yucca baccata var. vespertina 'Hualampai Blue'banana yucca
A new Cistus introduction. From our earliest days of botanically exploring the rich area from south western Utah to northern Arizona we’ve noticed the banana yucca, with forms there having upright, very blue leaves looking much like a misplaced sanseverria. This clone, from the south side of the Colorado river in Mojave County, is one of the bluest of the blue. Slowly offsetting clumps have upright leaves, to 4 ft or more, of pale blue adorned with curly filifers. The flowers, cream with nearly red bracts, rise to about 1/2 the leaf height ... but don’t hold your breath for the flowers. This is one of the prettiest yuccas we have come across. Tolerant of all kinds of miserable conditions including drought and poor soil but deserving decent drainage and little push of summer water in the driest spots. Frost hardy in USDA zone 4!

Yucca faxoniana - Albuquerque
Another of the tough Yucca faxoniana, this one collected near Albuquerque, New Mexico with the same 3-4 ft rosettes of stiff, emerald-green leaves, each leaf adorned with symmetric, pearly cream to brown filifers. 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. USDA zone 7 with some success in warm zone 6 with excellent drainage and protection from freezing winds.

Yucca filamentosa 'Bright Edge'variegated adam's needle
A handsome yucca, popular for its long, strappy and lax leaves, to 2-3 ft long, green-centered with gold margins and curly threads on the edges. Flowers are very showy, white on flower stalks to 12 ft tall. Excellent as a visual accent with leaf edges that aren’t sharp so it can line a path or border. Lean, well-drained soil in full sun with average summer water for best color, though tolerates some shade and some drought. Definitely frost hardy in USDA zone 7 and reportedly in USDA zone 5.

Yucca filamentosa 'Gold Stripe'
Discovered in the nursery as a striped sport of Y. filamentosa 'Gold Sword', each leaf adorned with very narrow creamy gold and blue green lines. Upright and vigorous to 18" in height and 3 ft or so across with, typically, 4 ft spikes of white flowers, most often in June. Full sun to dappled shade; otherwise extremely tolerant of any conditions thrown at it. Frost hardy in USDA zone 4.

Yucca filamentosa 'Hairy'
Dazzling form of this southeastern native selected at the JC Raulston Arboretum in the early 1990s and just now becoming available. Trunkless 3 ft rosettes of soft-textured but wide, blue tinted leaves are adorned with particularly large numbers of curly white threads, giving the entire plant a dazzling cobweb effect. Wonderful placed where backlighting occurs. One of the easiest to grow species in any soil, with bright light to dappled shade. Frost hardy in USDA zone 4.

Yucca filifera
Tree forming yucca and one of the most sculptural, the trunk eventually forming a swollen base and slowly branching. To upwards of 15 ft tall, with 2 ft rosettes of tightly held blue-green leaves covered with delicately intertwining filifers. Fabulous garden or container specimen for full sun and well-drained soil. Happy with summer moisture and winter drought, though quite versatile provided temperatures don't drop below 15F for extended periods. Cold hardy into the mid teens, mid-USDA zone 8; colder with exceptional drainage.

Yucca gloriosa 'Tiny Star'tiny star soapwort
Charming yucca, small and slow growing, to only 18" tall x 3 ft wide eventually, with variegated leaves, creamy yellow edged in green. Fits well into a rock garden. A selection of a southeastern US native, introduced from Japan in the 1970s by plantsman Barry Yinger, this form accepts the usual yucca conditions, sun to light shade, well-drained soil, and occasional water in summer for best appearance. So far, none have been seen to flower. Frost hardy to at least 0F, USDA zone 7.

Yucca gloriosa 'Tricolor'
One of the most useful of the trunk-forming, southeastern US native yuccas found growing from South Carolina all the way around to the Gulf side often within sea spray. With 2-3 ft rosettes of upwardly pointed leaves and trunks as high as 4 ft, this form has foliage variegated with cream and light yellow and infused with pinks especially with winter frost. Tolerant and even fond of average garden water and very long lived in container. Very good focal point for the garden. Has been quite happy and frost hardy to mid USDA zone 7.

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 linearifolia 'Dusky Blue'
One of the most beautiful yucca species, related to Y. rostrata. The 3 ft rosettes atop an eventual 3-8' trunk resemble the Australian grass trees, Xanthorrhoea, or a dim version of Dasylirion quadrangularis. Flattened somewhat triangular leaves of spring green to nearly turquoise and white flowers to 3' or so above the rosette. From only a few scattered localities, these from north of Galleana, NL, Mexico, in a most diverse habitat. This form is particularly blue and quite vigorous adding 6-8" of trunk each year. Our plant often elicits comments from garden visitors. The southern habitat of the species would indicate lack of frost tolerance but plants have so far withstood 5F, mid USDA zone 7. Full sun to partial shade and summer water with, as always, well-drained soil.

Yucca nana
Exquisite and tiny yucca from the San Rafael Swell of southern Utah. The 6-8" rosettes, with their undulate, glaucous blue leaves edged white, seem as if a bunch of blue star fish were playing leap frog. Slowly multiplying to form a small colony. Spectacular in garden or in pots: we have placed ours in a stone wall. Would love bright light and free draining soil, preferably high in mineral content, but, really, not very fussy. Small 2-3 ft spikes of pearly white flowers appear on mature plants in May and June. Frost hardy in USDA zone 4, if not 3.

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 'Gold Ribbons'
A Cistus introduction. This large growing native, from the Carolinas to the Gulf in sandy spots, forms a stunning rosette of weeping leaves and eventually a trunk to 4-5 ft. The plant is useful in all forms but Y. recurvifolia ''Gold Ribbons', can serve as a striking focal point or container plant with its blue dusted leaves and wide center strip of deep creamy yellow. We have used it as a substitute for the more spectacular, gold variegated, New Zealand flax (Phormium) in exposed or particularly frosty areas. Did we say spectacular? Fairly dry to quite damp conditions; decent drainage a plus. Full sun to dappled shade. Not advisable to let too many leaves collect in the crown if in shade. USDA zone 7; 6 in protected spots.

Yucca recurvifolia 'Margarita'
Fabulous yucca, evergreen with soft foliage, variegated in creamy yellow striped green with green edges. Very showy. Slow growing, to 4 ft x 6 ft eventually, with tall spikes of ivory bell flowers in summer. Best in full sun to part shade with occasional summer water for best appearance. Frost hardy in USDA zone 7. Recently changed from Yucca recurvifolia 'Margaritaville'.

Yucca rigida
Bold textured relative of the stunningly gorgeous Yucca rostrata, spending its very long youth as a 2 to 3 ft rosette of 1" wide, silver-blue leaves, eventually forming trunks to 5 to even 8 ft with small candelabras of white flowers in summer at maturity. This species from northern Mexico requires full sun to dappled shade in the most deserty areas and a touch of additional water in the driest spots. Not particular about soil as long as its not sitting in water. Our plants are putting on about 6" of trunk each season. Frost hardy in warm USDA zone 7.

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 7; has been successful in zones 5 and 6 including the Denver Botanic Garden (Really!).

Yucca rupicolatwist leaf yucca
This large textured species from the Texas hill country consists of slowly clumping, undulant leaves, 1 to 2" wide, of deepest green. Particularly striking when planted with silver-blues such as festuccas or other blue tinted, rosette-forming plants. An easy care creature if provided well-drained soil, supplemental summer water in exceedingly dry places, and bright light, though at home in dappled shade if leaves do not collect in its crown. Frost hardy in USDA zone 6.

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 thompsonianathompson's yucca
Charming tree yucca, reaching up to 8 ft tall x 4 ft wide with leaves that are stiff and powder blue with serrated margins and early summer flowers, white on tall stalks above the leaves. Related to and sometimes overlapping with Yucca rostrata though somewhat shorter and more branched, the multiple heads looking something like a miniature Joshua tree (Y. brevifolia). Full sun with good drainage and some summer water is best. Frost hardy to -20F, USDA zone 5 or even lower.

Yucca torreyitorrey's yucca, spanish dagger
Picturesque, very large yucca with leaves in excess of 4 ft, eventually forming a large shrub or small tree, usually single trunked, to 10 ft and taller with great age. Mature plants produce white bell flowers on 4 ft spikes, usually in spring but not every spring. Native from southwestern Texas to the mountains of Coahuila, Nuevo Leon, Mexico, this represents a particularly blue-leaved form from south of the border. Best with lean soil and good drainage in full sun or very light shade. Drought tolerant but faster growing with occasional summer water. Frost hardy to 0F, USDA zone 7.
Agavaceae $016 6in

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.

Zantedeschia aethiopica - super dwarf form
A very cute calla lily, given to us many years ago by Western Hills Nursery's Marshall Olbrich, and a very small, indeed, as the name suggests. To only about 20" tall and quickly clumping, with shiny green leaves that are only 4-5" across as are the typical white flowers. Easy among other perennials. Enjoying sun and well-drained soil, these are drought or standing water in the summer (only the summer!). Evergreen to 20F or so, USDA zone 9; root hardy to below 0F, into zone 6 if well mulched.

Zantedeschia aethiopica 'Hercules'hercules calla lily
A truly large form of calla lily that we obtained from Western Hills Nursery in Occidental, CA, bigger in both leaves and flowers -- and, of course, better. Leaves are spotted with cream dots and 8-10”, white flowers appear in early spring on stalks up to 6 ft tall. Full sun to part shade with adequate summer water. Frost hardy in USDA zone 7. Bulbs can be mulched or lifted in colder climates.

Zephyranthes 'La Buffa Rosea'giant prairie lily
This lovely rain lily, discovered in 1990 in Tamaulipas, Mexico by Yucca Do Nursery, begins flowering mid summer, producing multitudes of six-petalled, 3" stars on 12" stems in colors ranging from white to blushed pink to pink. The evergreen foliage is shiny and grass-like, to only 6-10" tall, forming clumps to 4-6" across. Wonderful as single plants or in drifts in sun to light shade with occasional summer water. Frost hardy in USDA zone 7. Thought to be a natural intergeneric hybrid between cooperia and cephyranthes, rain lily expert Thad Howard suggests the proper name would be x Cooperanthes 'Labufaroseas'. So far, zephyranthes remains the species, though the cultivar has many spellings, including variations on 'Labuffarosea'.
