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 to show 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!

Quercus hypoleucoides

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 silver 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.

Quercus turbinella
One of the most beautiful little oaks of the SW and another evergreen, this is a foothill chaparral plant from Arizona into southeastern California, just in Utah and barely touching Colorado. A shrub to small tree of only 6-12' ftwith small, somewhat spiny and revolute powder-blue leaves. These plants represent a collection from near Enterprise, Utah at 5,200 ft where temperatures frequently fall to 0ºF in the winter. Can be kept in container for many years, otherwise as garden plants. Expect 6-8 ft in as many years under ideal conditions: free drainage and bright sun and an occasional thunderstorm during monsoon season. This oak is a contender for USDA 6 but actually lives, as we write, at the Denver Botanical Gardens. Ours are young plants in 5" deep containers.

Skimmia arborescens
Unusual species; smaller, shrubby forms are indigenous to McDonalds and Burger King parking lots throughout the warm temperate world. As strange as it seems, this genus actually does have a habitat in moist woodlands of Asia, having sweetly scented flowers and quite attractive berries produced by the girls. S. arborea is a southern Chinese member of the genus that can grow to at least 20 ft in height with a very attractive umbrella shape and glossy evergreen leaves. Dappled shade, fertile soil with even moisture. Ours are unsexed, therefore quite under sexed, so possibly no berries. Received from the Kunming Botanical Garden some years ago, we do know that it has been a handsome garden plant and has grown to about 8 ft in ours. We feel reasonably confident of its aptitude for USDA zone 8 but not likely 7 or below.

Tetrapanax papyrifer 'Steroidal Giant' rice paper plant
A Cistus introduction. In 1997, plantsman extraordinaire Roger Warner gifted us this beauty, thought originally to be a dwarf after sitting in a gallon container for over a decade. Once planted in the ground, it sprung forth, revealing its bigger-in-all-parts self both in height and with sharper, bolder texture than the rice paper plant extant in North American gardens at the time. To 15-20' with 6'+ sharply-lobed leaves, slowly forming colonies, unless you don't want it do do so, in which case it can do so quite quickly. Actually, not as fast-spreading as the typical form, but will spread with root disturbance. The leaves are semi-deciduous, usually mid-December, with the stems having hardiness of up to 10 degrees more frost than the typical form. Sun or shade. Summer water. USDA zone 7 but has resprouted regularly from zone 6.

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'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.

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.

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.

Lighter rose-purple flowers appear on the tops of the stems, year round in container or out of frost, or from early summer on where plants are killed to the ground yearly. This one is a clumper not a spreader! Long used as container plants, it is also a must-have in richly colored garden where well-drained and watered soil can be provided and crowns do not freeze deeply. Can be reproduced yearly by emergency cuttings taken in fall, making sure to get a branched stem rather than one with only flower buds. Bright light to dappled shade.

x Fatshedera lizei 'Angyo Star'

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 $16 4D

x Fatshedera lizei 'Curly'

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.

x Fatshedera lizei 'Variegata'
The cream margined version of this Fatsia and Hedera hybrid. Excellent lax or self clinging shrub to about 6 ft.

Yucca 'Bright Star' PPAF/COPF
This mutant, an offspring of Y. gloriosa 'Variegata', has olive green and delightful, warm cream leaves, their variegation covering most of the leaf. Not as fast growing as its parent, but vigorous nonetheless. To about 18”, enjoying partial shade to full sun ... mostly shade in extremely hot summer climates. A definite bright spot in the garden or in container, it has been unfazed by temperatures of 14F and will probably go to about 10F, the bottom of USDA zone 8. Drought tolerant as with most yuccas but would enjoy occasional summer water to speed growth.

Yucca aloifolia 'Blue Boy'

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.

Frost hardy in USDA zone 5.
Agavaceae $15 4D

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.
Agavaceae $16 6in

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 whipplei var. parishii 6802
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.

Zauschneria septentrionalis 'Fiddler Silver'
A Cistus introduction. From an early 1990's collection atop southern Oregon's Fiddler Peak, the original plant grew in scree and reached only about 2" tall. Covered with relatively huge -- like about 1/2" -- orange-red flowers, with their chins resting on the ground. 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.

A small, deciduous shrub, to only a foot tall or so with very, very silver foliage. Perfect in a sunny rock garden or hillside with lean soil. These like a bit more summer water than their truly drought tolerant relatives, so occasional water where dry. (Occasionally included in the genus Epilobium.) Frost hardy in USDA zone 8.
