Quercus aff. rugosa - La Siberica strain
This is from our 1991 collection from high valley in Mexico's Nuevo Leon state and named for the town and the cold climate from which it comes. In habitat these form dense 6-8 ft shrubs with undulate and glossy fiddle-shaped leaves, deep green and ever so lightly furry above with a thick woolly coating of cream to light orange fur beneath. OoooH! Our original seed collections have grown in our somewhat more lavish conditions to 15 ft small trees just large enough tshow off the reflective undersides of the leaves. OoooH! OooH! From its habitat we suggest this might well be frost hardy into USDA zone 6 but we know zone 7 is a no-brainer. Ohhhhh, ohhh, ohhh!

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.

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 asiaticum 'Ogon'

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 to 10F, USDA zone 8.

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. Full sun to partial shade; at home in full shade but flowers more sparsely. Frost hardy to 0F, USDA zone 7, possibly even brief dips into upper zone 6.
Apocynaceae $14 4D

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.

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

Tradescantia 'Blue & Gold'

Tradescantia 'Blue & Gold'
Slow-growing spiderwort with soft, foliage golden -- more golden in bright light and more chartreuse in shady conditions -- and stunning, deep, iris-blue flowers, an amazing contrast over a long season. To 18" tall in clumps as wide. Can be cut back in summer to refresh and rehsape. Sun for best color or part shade with regular summer water. Easy in the garden, even enjoying very moist spots. Frost hardy to -20F, USDA zone 5. Also known as T. 'Sweet Kate.'
Commelinaceae $11 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.

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!
Agavaceae $16 3D

Yucca filifera

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 recurvifolia 'Gold Ribbons'

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.

Our collection, from southernmost California, of what we think is the subspecies, producing compact, powder-blue rosettes, somewhat hesitant to offset. To about 3.5' high and wide with stoutly spine-tipped leaves, perfect for directing the mailman from cutting across the garden. The plants flower after about a dozen years, if happy, producing few offsets. Very well-drained soil, though this species is considered the only truly winter-rainfall yucca. Full sun to dappled shade. Good air circulation in rainy places. USDA zone 8.

Zauschneria 'UC Hybrid'
Hybrid California fuschia from the U.C. Botanic Garden in Berkeley, or maybe not, with gray foliage and large scarlet blooms in summer and fall. Full sun and excellent drainage are must needs for this plant to thrive, though it can tolerate poor soils just fine. Height 12-18" and about 3-4' wide. Excellent for slopes and as a foreground plant in dry, sunny areas that receive little attention. Frost hardy to USDA zone 7, around 10 degrees.

Zauschneria californica 'Carman's Grey'

Zauschneria californica 'Carman's Grey'california fuschia
Masses of clear orange-red flowers cover this low, native, ground cover in late summer through autumn, just when you think the garden has gone to bed. To only 1.5 ft tall or so, this small, die-back shrub spreads by traveling rhizomes -- just enough to provide a lovely show. Best in full sun, little summer water once established, and soil that drains well, e.g, a hillside planting. This form, selected by Ed Carman for its silver foliage and particularly bright flowers, is frost hardy to 0F, USDA zone 7. Also known as Epilobium canum 'Carman's Grey' but we still think "zauschneria' sounds prettier.
