Acacia cultriformis knife-leaf wattle
Widely cultivated tall shrub, 6-10 ft, from Australia. Drooping branches with blue-gray, almost triangular leaf-like phyllodes (flattened leaf stalks) held close to the stems. Perfumed, rounded clusters of bright yellow spring flowers on long sprays. Excellent for hedging. Full sun. Drought tolerant once established. Thought to be frost hardy in USDA zone 8 but difficulties in the recent hard winters suggest upper zone 8, e.g., so best where protection can be provided in cold winter moments.

Alnus formosana [Tayuling 2004] formosana alder
Native to Taiwan at mid to high elevations, this was of interest to us for its evergreen habit, the glossy green leaves holding fast, we expect, in temperatures down to 18 to 20F. Though loving damp conditions, these do not require quite the riparian situation of many alders. Fast growing, to 30-40 ft tall, in sun to part shade with summer water. Stand back! Ultimate cold hardiness is not yet tested but these will remain healthy, though deciduous, to the bottom of USDA zone 8.
Betulaceae

A Cistus introduction. From Northern Lake County California "amid a grove" of like-minded manzanitas, this form is particularly large -- to 15 ft or more but easily maintained at 4-5 ft -- with an upright habit, red stems, and green leaves slightly tinted mauve. Outstanding as a backdrop with very pale pink flowers occurring anywhere from the end of December through February.

Salicaceae

Banksia integrifolia

Banksia integrifolia
Loveliest large shrub to small tree from southeastern Australia. This handsome protea, to about 15 ft or even more, has beautifully serrate leaves when young, later on becoming nearly entire with reflective, silver-white undersides. Once plants reach 3-4 years of age, "corncob" flowers appear, to 4-5" tall, held upright as candles. To us they smell of baking bread or...corn. To their pollinators, I suppose baking bread would smell very much like a banksia. Reliable in upper USDA zone 8; freezes back to its lignotuber at 15F. Where temperatures fall below, keep in a pot to bring inside. Bright light to dappled shade in sandy soil. As with all proteas, watch the phosphorus. We fertilize ours with alfalfa pellets.
Proteaceae

Buddleja colvilei 'Kewensis'

Buddleja colvilei 'Kewensis'
A very old cultivar of this "best of the buddlejas", selected at Kew Gardens for it's darker-than-the-species red flowers in lovely and lush terminal panicles during the summer. Same pointed and felted leaves as the species and a similar size, e.g. quickly to 10-15 ft tall, so a very large shrub to small tree needing lots of room. (This species resents the severe pruning that keeps its cousins smaller.) Best in full sun and well-drained soil with regular water and protection from wind. Evergreen in mild climates and frost hardy in USDA zone 8. Resprouts from the roots in zone 7.

Ceanothus 'Oregon Mist'

Ceanothus 'Oregon Mist'california lilac
One of the best new ceanothus introductions, this collected from near Cape Blanco on the Oregon coast by plantsmen Paul Bonine and Greg Shepherd. Though originally thought to be rather diminutive, our plants have grown to nearly 15 ft in 6 years, so we now declare it a small tree adorned with delicate, 1/3” green glossy leaves and dusky blue flowers throughout the year in mild climates and especially in spring and fall with inland heat. When pruned into standards, the delightful green bark can be exposed, sure to elicit squeals of delight at your next open garden. Sun to light shade. Tolerant of some summer garden water but long lived and slower growing without water. Frost hardy in upper USDA zone 7, at least.
Rhamnaceae

Has grown to 25 ft so far with a narrow upright form. Requires dappled shade to full sun with summer water in dry climates. Appears tough and frost hardy to at least the top of USDA zone 7 (Cinnamomum parthenoxylon is a synonym.)
Lauraceae

Cinnamomum porrectum - Cliff Parks Coll/Avent

Cinnamomum porrectum - Cliff Parks Coll/Avent
One of the loveliest of the cinnamomums and, as luck would have it, the most frost hardy. This clone, a tree to 20-30 ft from Tony Avent's garden, has 2", quaking aspen-shaped leaves that are shiny green above and blue beneath – with, indeed the aroma of camphor where brushed or crushed. Stems, often red tinted, add to the excitement. This might be one of the best new broadleaved evergreens in … weeks. Happy if provided dappled shade to full sun and occasional summer water in driest places. Has been frost hardy – make that freeze hardy with no leaf damage -- to under 10F, uppermost USDA zone 7.
Lauraceae

Citrus ichangensis

Citrus ichangensisichang papeda
Wonderful large shrub that can be pruned into a small tree, to 8-10 ft or more. Narrow, evergreen leaves and, believe it or not, attractive green branches and spines. Fragrant flowers produced in spring and summer become small orange ...uh... oranges that are a bit bitter for eating out of hand but fine made into juices in times of famine. Really, we grow it for the look. Sun to dappled shade. Has survived temperatures below 0F. We consider it frost hardy to 10F, the USDA zone 8 range, if water has been withheld in autumn for hardening.
Rutaceae

Clerodendrum trichotomum 'Golden Glory'

Clerodendrum trichotomum 'Golden Glory'golden glorybower
Though having much the same shape as the species, this slightly smaller cultivar, to 10-12 ft with umbrella form, has striking golden leaves often tinted orange when emerging and fading to spring green in mid to late season. Fragrant white flowers appear in mid to late summer followed by metallic blue, red-bracted fruit. A handsome addition to the garden in bright light for best color and at least occasional summer water where dry. Can colonize with root disturbance - a good or bad thing. Frost hardy to 0F, USDA zone 7.
Verbenaceae

Clerodendrum trichotomum 'Spring Purple'

Clerodendrum trichotomum 'Spring Purple'spring purple glorybower
A purple-flushed leaf form of the classic harlequin glory bower. This form found in an old Portland garden courtyard by Josh McCollough. Having slightly smaller leaves with great purple coloring in the spring, slowly greening with more purple returning on new growth in summer. Likely the variety; C. trichotomum var. fargesii. A good street tree for Portland, though seldom used, with sweet smelling, white flowers in late summer, perfuming the neighborhood especially at night. Turquoise berries framed by crimson bracts add to fall fun. Foliage is aromatic as well -- think peanut butter. To 10 ft tall or so in full sun for best flowers and fruits and water occasionally in summer. Planting in reach of a lawn mower eliminates pesky suckers. Easily frost hardy in USDA zone 7.

Fairly columnar and multi-stemmed, to 10 ft tall x 5 ft wide, these are best planted away from paths where their prickly foliage may be experienced too closely. Full to part sun with some summer water, though somewhat drought tolerant when established. Frost hardy to 0F, USDA zone 7.

Malus sp. - Taiwan
Collected some time ago from the highlands of Taiwan by plantsman Philip McDougal, this small, 15 ft tree has been quite striking in our garden with its flattened top and deeply dissected leaves that begin turning saturated tones of orange and red in late December, usually holding through winter. Our plant has not yet flowered or fruited for us so stay tuned for more information. Full sun for best color and occasional summer water where dry. From our experience, frost hardy in USDA zone 8a.
Rosaceae

Maytenus boaria 'Green Showers'

Maytenus boaria 'Green Showers'mayten
Evergreen tree, to 30 ft tall and wide over time, with a weeping habit and bright green, dense foliage, the leaves finely toothed. Flowers are small but fragrant, green and star-shaped in summer, and followed by a few red berries in this femal form. Grows fastest in good garden loam, up to two feet per year. Should be watered deeply every two weeks to encourage deep roots and discourage suckering. Best without mulch. Frost hardy to 0F, USDA zone 7.
Celastraceae

Metapanax delavayi 'Stout'

Metapanax delavayi 'Stout'stout delavay false ginseng
A Cistus introduction. Selected from our seed grown plants, this clone of an already desirable evergreen aralia relative, has rather thickened compound leaves, more schefflera-like than its brethren. A graceful shrub or small tree, these have a sturdy form, maintaining an upright stance. Mature plants produce late summer clusters of white flowers that become black berries providing winter food for the birds. Dappled sun to part shade and rich, moist soil are best. Frost hardy to upper USDA zone 7 and possibly lower. (The species, until recently, was Nothopanax delavayi.)

Metrosideros kermadecensis 'Variegata'
Evergreen shrub to small tree, to 4-6 ft tall, with variegated foliage, shiny green with cream especially on the leaf edges. Brilliant red, brush-like flowers are gorgeous in late spring to mid summer. Prefers full, hot sun and accepts both consistent moisture and periods of drought once established. Does well in windy, coastal conditions. Tolerates only light frost in USDA zone 9 so, where winter frosts are usual, best in a container that spends its winters indoors.

Nyssa sinensis chinese tupelo
A lovely and vigorous form of the deciduous swamp tupelo, this chinese species grows taller, to 40 ft or more and half as wide, with apical dominance (uprighteousness...) maintained much more easily than our native North American species. Sun to dappled shade. Best with summer water but tolerates some drought. Also sits happily in winter water. Fall colors are vibrant red to deep oranges to gold. Frost hardy in USDA zone 7.

Olea europaea 'Mission' mission olive
Long planted in North America, a reliable plant with an overall handsome habit. To 15-20 ft, though untended specimens have reached 40 ft, with 2" silvery leaves and deep black fruit ripening late. Sun in well-drained soil. Supplemental water to establish; withhold in late summer to harden. Has remained hardy to 10ºF, USDA zone 8 if fully ripened.
Oleaceae

Osmanthus x fortunei 'Ninth & Polk'

Osmanthus x fortunei 'Ninth & Polk'fortune's osmanthus
Possibly a very mature Osmanthus x ‘San Jose’ but appears to have a more rounded form and much wider leaves,scalloped and gently toothed. Ours are from a plant appearing to be at least 100 years old in Corvallis, Oregon. The lovely form and quite abundant flowers in late October led us to ask permission (yes, really!) for cuttings several years ago. A wonderful creature for small specimen tree to 12-15 ft eventually, or hedging or screen. Drought tolerant once established. Frost hardy in upper zone 7 in bright light to dappled shade.

Osmanthus yunnanensis Yunnan tree olive
Handsome and rare in cultivation, this evergreen large shrub or small tree has leathery, slightly toothed, olive-green leaves and scented, near-white, waxy, axillary flowers in late winter to early spring. Slow growing plants can reach 8-10 ft tall x 6-8 ft in a reasonable time; larger, to 20-30 ft tall with great age and no pruning. Bright light, with protection from hottest sun, in rich, well-drained soil with regular summer water. Frost hardy in USDA zone 8. Said to be deer resistant plant when mature.

Peumus boldus - clone 2

Peumus boldus - clone 2boldo
Small, slow growing, evergreen tree from dry sunny slopes in Chile. The aromatic leaves are shiny, 1-2.5”, dark green above and paler beneath; the summer flowers off-white, appearing in clusters; and the fruits (drupes) red -- but only set if a suitable friend is nearby. Sun to part sun with little added summer moisture and well-drained soil. Frost hardy to 10F, USDA zone 8, a protected location.
Lauraceae

Photinia serratifolia var. serratifolia

Photinia serratifolia var. serratifolia
From China, this handsome and useful big, bold, glossy leaved evergreen can be grown as a large shrub or trimmed as a small tree -- to 12-25 ft x 10-20 ft. Leaves, 4-8”, emerge light green and bronze tinged maturing to dark green and leathery with serrated margins and lighter undersides. Large clusters of bright red berries in autumn follow the early spring panicles of white flowers, lovely, though their aroma is not universally admired. Sun to part shade in well-drained soil. Drought tolerant but accepts and appreciates some summer water. USDA zone 6.

Pinus eldarica Afghan pin
This dark-needled pine, from Russia and Afghanistan, loves dry conditions, growing quickly when young, eventually reaching 30-80 ft tall by 15-25 ft wide with a symmetrical form, rounding on top over time. Needles are 6" long in sets of two and occasionally 3. Tolerates poor soils but good drainage is best for long term health. Drought tolerant once established, but accepts occasional deep watering, in full sun inland or on the coast where plants tolerate windy conditions. Frost hardy to -10, USDA zone 6.

Pinus ponderosa - Willamette Valley Collection ponderosa pine
Beautiful, massive native tree, these from plants that grow in the Willamette Valley. Needles are up to 10" long. Bark is very dark brown when young, maturing to a yellow-red-brown, becoming very thick and furrowed, breaking up into "jigsaw puzzle" like pieces. Eventually reaches 175 ft but not quickly. Adapted to full sun, well-drained soil and little or no summer water once established. Frost hardy to -40F, USDA zone 3.

Pittosporum patulum

Pittosporum patulum
A most unusual member of the genus from New Zealand southern South Island, endemic to only a couple of spots along the Bellcloutha River. Growth is narrow and upright to 8-15' with black, spidery leaves in youth enlarging only somewhat in adultitude with more rounded bright green leaves and a multitude of deep maroon flowers said to be the most fragrant of the genus, reminiscent of carnations. This should make a fine new addition to the garden, especially the Goth garden. We have surmised hardiness to zone 8 that has been verified by surviving 12F in winter 2014 in the garden of our super friend Loree, where she and the plant survived the winter unscathed.
Pittosporaceae

Plagianthus regius lowland Ribbonwood, manatu
Lovely small, deciduous tree from New Zealand, to 20 ft tall x 6-7 ft wide, that begins as a dense shrub with interlaced branches and matures to a graceful, upright, adult form with lateral branches and wavy, nearly black stems holding toothed leaves. Pale yellow-green flowers appear in late spring in large panicles. Tolerant of poor soils and dry conditions but enjoys consistent summer moisture. Dislikes intense summer heat with humidity. Perfect for the sunny coast or in dappled shade inland. Surprisingly, specimens from Cistus took single digits in several places in the winter of 2009 so we expect hardiness to frost in USDA zone 8.
Malvaceae

Podocarpus chinensis - Yucca Do

Podocarpus chinensis - Yucca Do
Though the name is somewhat questionable, the plant is certainly not. Given to us by Yucca Do Nursery some years ago, this Podocarp spends several years as a delightful conical shrub with narrow, spring green foliage of about 1” in length; we are told it can eventually grow into a large tree of 30’ or more. So far this gem has withstood temperatures into the upper single digits Fahrenheit with no visible damage. We find it, however, thirsty for some summer water in our part of the world.

Polyspora macrocarpa DJHMV 041
These are lovely Asian counterparts to the gordonia, large shrubs to small trees reaching 15-20 ft or more in a reasonable time with evergreen, glossy, 4-5" leaves emerging orange then, in late summer, framing clusters of 2-3" fragrant white flowers with a generous boss of yellow stamens. All of this and stewartia-like bark as well! Prefers full sun in coastal areas to dappled shade inland and well-drained soil with occasional summer water where dry. This form has so far proven frost hardy in the garden to the bottom of USDA zone 8 with overhead protection.

Rosaceae

Prunus ilicifolia

Prunus ilicifoliaholly leaf cherry
A cherry for the dry garden with dark-green, holly like leaves and attractive, white flowers in July followed by late autumn fruit (more pit than cherry). A chaparral plant from Oregon's Siskiyou Mountains and southward, this dense, evergreen shrub or small tree, to 5-10 ft, is an important wildlife habitat and food source. Best in full sun with little summer water. Undamaged into the mid teens F, mid USDA zone 8.
Rosaceae

Prunus lusitanica

Prunus lusitanicaportuguese laurel
Think gorgeous, small, evergreen tree to 10-20 ft tall and wide with shiny, dark green leaves.. These are cherries, blooming in late spring in tall racemes of white, fragrant flowers. Purple-red berries ripen to black in autumn -- bitter so best left to birds. Can be grown as a large, multi-stemmed shrub. Sun to part shade with normal summer water to establish. Frost hardy in USDA zone 7.

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!

Quercus chrysolepis SBH 7192 canyon live oak
And extremely handsome, evergreen oak, native from southern Oregon south into Mexico and Baja California, this form from acorns collected at the confluence of the Trinity and New Rivers in Northern California. A tall, vase-shaped tree, to 30 ft or so in your lifetime; taller over its very long lifespan. Extremely drought tolerant making it an excellent street tree. Somewhat shrubby in its youth but worth the extra care to encourage leader growth. Plant in bright light in deep soil and enjoy! Frost hardy to -20F, USDA zone 5.

Quercus glauca japanese blue oak
Previously Cyclobalonopsis glauca. Beautiful oak, or oak relative depending on one's taxonomic belief, from southeast China to Japan and Taiwan. This blue-tinted creature can reach 60-80 ft but seems content at 20 ft in our part of the world. It had a brief stint of popularity in Portland in the 50s, then as far as we can tell, became almost completely unavailable. The silvered bark and blue undersides of the leaves make this one of the prettiest, medium-sized garden trees available for warmer climates. Not fussy but likes supplemental summer water in dry climates. Good for sun or shade. Frost hardy in upper USDA zone 7. (The beautiful specimen at the JC Raultson Arboretum in North Carolina was damaged severely but recovered quickly at around -8º F.)

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 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.
Fagaceae

Quercus ilex

Quercus ilexholly oak, holm oak
Native to the Mediterranean, frequently grown as far north as the British Isles and occasionally in the western US. This olive green, silver tinted, medium to large tree, to 25-40 ft ft (more in a few hundred years) is most exquisitely adapted to dry summer climates and is a wonderful constituent of that Mediterranean look, just throw in an Italian cypress and some olives. Requires only well-drained soil and temperatures not falling below 0 to 10F, USDA zone 7, for any length of time. Not absolutely happy with the summer heat and humidity of the US Southeast unless in well-drained, exposed situations.

Quercus sadleriana - Bear Camp Summit sadler oak, deer oak
One of the handsomest of the western, evergreen oaks, this native of southwest Oregon to northern California is a small shrub, to only 6-10 ft tall x 3 ft wide, with huge, shining leaves, oblong and serrated, dark green above and paler beneath. Best in well-drained soil in understory conditions in light shade. Tolerant of summer drought and hot conditions as well as heavy winter rains. Frost hardy in USDA zone 5.

Quercus suber

Quercus suberCork Oak
The famed cork oak from the savannas of southwestern Europe, indeed used for repeated harvest of the real thing! Coming from our mirror climate, this makes a most beautiful and useful street or garden tree, reaching an eventual 50 ft, with thickened, orangey bark and rounded, evergreen leaves, somewhat shedding briefly in early spring as the new leaves emerge. (By the way, pigs love the acorns ... just saying.) Accepts a fair amount of garden water but most at home with long summer drought. Frost hardy in USDA zone 7.

Rhamnus alaternus 'John Edwards'

Rhamnus alaternus 'John Edwards'italian buckthorn
One of the most versatile, durable, easy, and drought tolerant plants for Mediterranean climates, this selection having come from Tilden Park in Berkeley, California. Small tree, to 20 ft, or large shrub, to 12 ft, easily trimmed as a handsome hedge. Evergreen leaves are small, crinkley, and dark green; greenish white flowers also small, and produce black berries adding texture. Full sun with very little summer water. Frost hardy to 5F, USDA zone 7b.

Schefflera arboricola BSWJ 7040

Schefflera arboricola BSWJ 7040dwarf umbrella tree
Nice, five to nine leafletted evergreen from southeast Asia collected by famous plants hunters Bleddyn and Sue Wynn-Jones. Exciting and unusual. Can be pinched for a compact shrub or pruned as a small tree and allowed to reach its full height of 10-15 ft over time. Best in partial shade with rich soil and regular summer water. Frost hardy in USDA zone 9B. A find pot specimen where temperatures drop into the low 20sF.

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.

Taxodium mucronatum - historic New Mexico population

Taxodium mucronatum - historic New Mexico populationmontezuma cypress
A tall, handsome, Mexican native tree, to 50 ft or more by 30-40 ft wide and semi-evergreen, with a spreading crown, horizontal branches, and weeping foliage. Prefers sun to part sun and lean soil with regular summer water, though tolerant of summer drought. The Montezuma cypress was once thought to grow only in warmer climes of USDA zone 9 or so, but these plants, cutting grown from seed collected off 500 year old trees at 5000 ft in New Mexico, are very happy in the Pacific Northwest USDA zone 8. Taxodium huegelii is a synonym accepted by some as the proper name.

Trachycarpus fortunei - precocious fruiting form Chusan Palm
Shared with us by great Texas plantsman, Scott Ogden, this little fella forms a short trunk that, though eventually growing to typical chusan palm size, forms a dense crown and flowers after only a few years from seed, producing heavy amounts of blue black fruit on yellow stems -- of great ornamental value. Full sun to only lightly dappled shade. Summer water for best growth. At least as typically frost hardy, to 0F with some reports of -10F. Five year old plants in 6" long pots.
Arecaceae

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.

Umbellularia californica [Fresno, CA]

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.
