Quercus berberidifolia SBH 7197 california scrub oak
One of several shrub or chaparral oaks from western North America. This form, one of our collections from the southern Siskiyou mountains, reaches 6 ft, though can be encouraged to a miniature tree to about 8 ft tall by pruning off excess branches. Somewhat spiny and leathery, downward-cupped leaves held closely together make this a most attractive garden subject. Loves hot, bakey, Mediterranean conditions but seems to thrive in a watered garden as well. Frost hardy to 0F, USDA zone 7.

Quercus crassipes

Quercus crassipes
From central western Mexico at about 7000 ft elevation this oak with rather long, leaves, hispid (hairy) above and pale underneath, and a silvery trunk was given to us by plantsman Alan Taylor. We expect it to make a very pretty, horizontally branched tree to about 35 ft tall, tolerant of long periods of drought and evergreen save for, possibly, a brief period in spring as new growth begins to appear. From its location we are guessing frost hardiness to 10F, USDA zone 8, but many of these oaks have surprised us with their ability to stand cold.

Rhamnus alaternus - Portuguese clone

Rhamnus alaternus - Portuguese clone
This most attractive shrub, originating from Portugal's National Botanical Garden, ranges to 8 ft tall or a bit more with 1/2". ever-so-slightly silver-tinted, evergreen leaves. Flowers are insignificant and, in our experience so far, the fruit is negligible as well. But we like the plant itself, smaller and more fine textured than other forms and useful for screening and for specimens in the summer dry garden. Fine in sun to only lightly dappled shade and in most soils save for those sitting in winter water. Frost hardy to 0F, USDA zone 7.

Ribes 'Pink Pearl'

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.

Sabal palmetto cabbage palm
From seeds shared with us by fellow plant nut, Hayes Jackson, in Aniston, AL, from his quick growing specimen, one having survived a couple of dips below 10ºF no worse for wear. The state tree of South Carolina, this stately palmetto reaches 30 ft or more, though quickly in the southeast, quite slowly in the cool summer night West. Lovers of heat and consistent summer moisture: fast growing in any hot-summer-night area and slow to form a trunk elsewhere. Because it stretches from the coast of the Carolinas to the Gulf to the Caribbean, we are always on the lookout for northern forms. "Don't be dumb, get you some" -- Hayes Jackson 2002.

Sycopsis sinensis - narrow leaf form
Selected from a seed batch, this graceful large shrub to small tree, reaching to 15 ft tall or more with silvery bark and horizontal branches, has, instead of the long, oval, deep green leaves of the species, leaves of 1/4" x 3" leaves, making this collection quite distinct. Small clusters of reddish flowers, similar to its cousins the hamamelids, appear in winter - not very flashy but lovely up close. Very good for screening or a small garden specimen in shade to sun, though we find it somewhat more graceful in at least afternoon shade. Prefers some summer water where dry. Frost hardy to 0F, USDA zone 7, possibly colder.

Trachelospermum 'First Snow'

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 to 0F, USDA zone 7.

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 to 10F, USDA zone 8.

Trachelospermum asiaticum 'Hatsuyuki'

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 to 0F, USDA zone 7. Also useful as an indoor plant.

Trachelospermum jasminoides 'Madison'

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.

Trachelospermum jasminoides 'Variegatum'

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 to 0F, USDA zone 7.

Trachelospermum sp. - Cliff Parksstar 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.

Trachycarpus takil kumaon fan palm
A vigorous chusan palm, grown from closed pollinated seed originally collected by Hoffman years ago in Mt. Takil. The adult plants have exceptionally large fronds, standing upwards of 4-5 ft and bending in a uniform manner giving the tree a robust and almost weeping effect. Growth is quick, sometimes more than 18" of trunk per year in happy times. It is possible that these tend toward similar palms growing nearby and now called T. nova. Elegant in any case, in sun or 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 $12 4D

Trachycarpus wagnerianus

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.

Tradescantia 'Gold Crest'

Tradescantia 'Gold Crest'

This West Coast native is low growing, to only 8-12" tall, and produces charming tiny white flowers with a spot of red dangle in spring. Shade is best, possibly some morning sun, in fertile soil with mulch. Needs water to establish and tolerates prolonged drought thereafter. Evergreen in USDA zone 8; root hardy to -10F, zone 5.

Verbascum undulatum

Verbascum undulatumwavy 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.

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 to 0F, USDA zone 7.

Yucca baccata var. vespertina 'Hualampai Blue'

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

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.

Zauschneria septentrionalis 'Fiddler Silver'
A Cistus introduction. From an early 1990s collection atop southern Oregon's Fiddler Peak, the original plant growing in scree and reaching only about 2" tall while covered with relatively huge -- like about 1/2" -- orange-red flowers with their chins resting of the ground, awaiting hummingbirds doing bellyflops to come and pollinate. The leaves are indeed silver hued, a nice contrast with the July to late autumn flowers. At low elevations, plants spread vigorously but remain quite short. Winter deciduous in bright light and well-drained soil with little summer water once established. Expected to be frost hardy to -20F, USDA zone 5, or possibly below.
