Aralia californica

Elk Clover. Our native large herbaceous Aralia that forms large, tropical-looking clumps along moist places in the central southern part of the state. To 8′ tall and as wide when established in rich soil  with an adequate summer moisture supply. A native plant that takes very well to cultivation. In summer 2′ long spikes reveal white orbs. Showy and a little exotic for a native as well. This is a great large scale plant for tropical effects- mix with Hardy Banana (Musa basjoo) and you have got yourself a big bold look. Black berries follow the flowers and are somewhat showy as well. Completely winter deciduous. Oregon native plant.

Arbutus menziesii

Pacific Madrone, iconic tree of the Pacific Northwest. Famous for its glossy, russet orange, sinuous, exfoliating bark and round, evergreen foliage. In spring, clusters of white flowers are showy and turn into vivid red berries by autumn. These are loved by birds- especially western tanagers who will quickly strip a tree as flocks move from one to the next. Must be grown from seed and it must be transplanted when small. Just the way it is. Plant it in average, well drained soil. Water lightly through the first summer in subsequent years leave it strictly alone. Full sun is best- tends to wander towards the sun in shade. Underplant with low water natives such as Arctostaphylos, Ceanothus, Vancouveria. Slow at first it picks up speed after about 4 years- then it can grow 2′-4′ a year. Somewhat messy tree- loses leaves in summer and the bark exfoliates all over the place too. Know this and live with it. Ours are raised from seed of trees native to our wholesale nursery site- so its a local strain. Oregon native plant.

Arctostaphylos ‘Greensphere’

Very cool and tough Manzanita that is a true dwarf and therefore it is slow to get to market. We anticipate having more of this dense growing, cold hardy, disease-resistant  shrub. To 30″ x 30″ with great age forming a perfectly round sphere. New growth is bright red settling to blue green. Leaves are held densely on the stems. Full sun and good air circulation in average, well-drained soil. Excellent cold hardiness to near 0ºF. A natural for hellstrips or anywhere space is a premium. Pink flowers in late winter are showy and profuse. Mahogany glossy bark- in time. Very limited quantities. Probably available in autumn.

Arctostaphylos ‘Monica’

She’s a big girl, but so pretty and adaptable and easy we love her. Soaring to 9′ tall and almost as wide the pretty, large, deep forest green foliage is particularly disease resistant. In late winter to early spring profuse clusters of pink flowers transform into russet berries (bird food). Fast growing shrub with amazing glossy mahogany stems and trunks. Full sun, well drained to average soil with no summer water. One of the most garden tolerant of the gigantic cultivars. Cold hardy to at least 5ºF. Spectacular turned into a small tree.

Arctostaphylos auriculata ‘Diablo’s Blush’

Excellent garden-tolerant smaller Manzanita. New growth is blushed pink as are the winter flowers. Settling to soft gray, this dense rounded plant achieves about 3′ x 3′ in 7 years. The bark becomes reddish and shaggy with age. Full sun and very well drained soil with no supplemental water once established. Gray foliage is organized symmetrically around the thick stems.  This is a good scale for smaller gardens and a handsome shrub at all times. Provide good air circulation in an uncrowded environment. Long lived.

Arctostaphylos bakeri ‘Louis Edmonds’

One of the most picturesque Manzanitas, this selection bears lovely gray-green leaves that are nearly circular, held perpendicular to the stems. The bark is one of the best of all species and selections, deep burgundy/purple and smooth. Vivid pink flowers that appear in late winter to spring transform into small russet red apple-shaped fruits. To 6’ tall and 4’ wide in 5 years. Requires well drained soil with little additional irrigation when established. Cold hardy. Good looking year round.

Arctostaphylos canescens var. sonomensis

Our very, very favorite Manzanita and one of the very rare ones in the wild. Occurs on two ridges in northern California- Horse Mountain was one of them and Greg’s dad just happened to have a cabin there. Low, dense, spreading, very gray shrub to 3′ x 5′ wide in time. The bark is a great glossy mahogany and the winter/spring flowers are white tinted pink. Russet berries are quickly consumed by wild life.  Spectacular shrub for full sun, average to poor, well-drained soil and absolutely no summer water. Loathes the combination of water and heat. Neglect is its friend and you will reap great rewards with this beautiful shrub by strictly ignoring it once it is established.  Ultra cold hardy- hailing from over 4500′ in elevation  and recommended for cold gardens. This species is native to southern Oregon, and though not technically native to Oregon this is our favorite form of this species. Not the easiest to propagate so quantities are often limited. Absolutely NO summer water. Ever. Forms rounded balls of soft silver. Dynamic on slopes.

Arctostaphylos columbiana ‘Parkdale East’

This form of our native Hairy Manzanita was found quite far east of the Cascade crest and offers greater hardiness to cold. Unfortunately, it has the same characteristics of the species- it is unpredictable. To 4′ x 7′ with sage gray leaves and white to pink-tinted flowers in spring. Very well-drained soils in an open position with NO summer water when established. Dramatic smooth mahogany bark is an outstanding feature. This is the variety that is best suited to life in the Columbia River Gorge and possibly eastern Oregon. Best with total neglect and full sun. Russet berries follow the flowers into summer and autumn- always consumed by wildlife. Very limited quantities.   Oregon native plant.

Arctostaphylos columbiana ‘Wolf Creek’

Our native Hairy Manzanita is one of the most widespread species in the PNW. Unfortunately, its not the most reliable and can be kind of hard to grow. It will grow happily for years and then suddenly decline. No explanation.This can be avoided by strictly avoiding all irrigation once established.  Large-growing shrub with gray green leaves, the telltale hairy leaf petioles and white flowers in spring. Russet berries follow. Its best attribute is its smooth exfoliating mahogany bark. And in time you can remove the tired lower branches to reveal it as well as improve air circulation.  To 8′ x 8′ very quickly in average, well-drained soil. No summer water and little intervention from the gardener. Wild areas, dry hillsides. This form we selected from the southern Willamette Valley. It occurs in specific sites around the Valley and is common at the coast /coast range as well as the Cascades. During the warm interstadial (4000-8000 yr BP) when our climate was considerably milder with a much more pronounced summer drought it was much more widespread- once found in the city limits of Portland at two sites those have been usurped by development. Excellent performance in hot dry urban sites. Oregon native plant.

Arctostaphylos hookeri ‘Wayside’

At the North Willamette Experimental Station in Wilsonville  where OSU conducted a trial of scores of Arctostaphylos species and cultivars this special ground cover Manzanita has been consistently one of the best performers. Deep green pointed leaves are held perpendicular to the sun on cinnamon red stems. In time it forms glossy red bark that is very showy. Low and dense growing to 2′ tall and 6′ wide. Excellent bank cover or ground cover in any soil that is not amended or boggy. Profuse white flowers in spring. First rate weed suppressing plant for hellstrips, rock gardens, dry borders. Excellent appearance year round. No summer water. Take advantage of its low dense growth to cover and suppress weeds. Wonderful plant for the baking hot locations.  Very easy to grow.
