Agave parryi ssp. truncata

Agave parryi ssp. truncata

Consistently one of the most successful Agaves for gardens in our region. Soft gray rosettes have leaves with a distinct upright habit. At the tips of the wide leaves is a single (deadly) black thorn. Very nice. Full sun and very well drained soil with little to no summer water when established. This Agave requires soil that is never soggy- amend heavily with pumice and gravel to create air pockets. Plant this (and all) hardy Agaves in our climate on a tilt. The tilted rosette sheds rainwater and it keeps it much drier in winter. Ideally, this Agave should be sited on a hot, south facing slope. In autumn deciduous leaves from (everywhere) seem to blow into the rosette and collect. You must remove these immediately so that they do not rot the center of the plant. A shop vac works wonders…so do bar-B-Q tongs. Excellent in containers. Its best to plant hardy Agaves in early spring to early summer. They require a long season to develop a tap root which in turn ensures that they are cold hardy. No tap root and not so hardy. Hardy below 0ºF when dry. Highly deer resistant.

Aquilegia chaplinii

Native to the Guadalupe Mountains of New Mexico and extreme west Texas this adorable columbine enchants us with its whimsical soft yellow flowers and fine blue foliage. To 18″ tall in bloom the petite flowers have long fantastic tails. They appear from April-June, and occasionally again if you remove spent flowers and prevent seed set. This smaller plant has wonderful finely divided blue green foliage that forms a fountain before and after bloom. Often self sows in open sites. The original plants live about 5 years but the distinctive leaves will give away the seedlings. They seem to favor cracks in pavement, stones. Full sun to very light shade in rich to average soil with regular summer water. Mix with our native Columbine (Aquilegia formosa) for a color echo on the yellow perianth of both. Very popular with pollinators including native pollinators. Winter deciduous.  Moderate deer resistance. Charming and easy to grow wild flower.

Aquilegia x ‘Xera Tones’

A little wacky columbine sex in our nursery between our native orange and yellow flowering Aquilegia formosa and the brown and green flowered (and fragrant) Aquilegia viridiflora. The color range of the flowers is truly insane. And many of them are fragrant. They also have inherited the very good leaves of A. formosa- which are decidedly blue and delicate looking. They appear to be long lived perennials just as their parents and you just know that these buggers are going to reseed themselves. Part shade to full sun with regular water.

Aralia californica

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. Native to the southwest part of the state with a disjunct population in the Cascade foothills of Lane county.  Oregon native plant.

Arbutus menziesii

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 older 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. Pacific madrone is native from the highest mountains of southern California to southern British Columbia. It is the northern-most broadleaved evergreen tree (native) in North America. Oregon native plant.

Arctostaphylos glandulosa ssp. glandulosa 'Demeter'

Arctostaphylos glandulosa ssp. glandulosa ‘Demeter’

Our employee Adinah spotted this distinct form of our native glandular manzanita in extreme SW Oregon. This form boasts very silver foliage with sharply pointed leaves and the conspicuous glands that identify the species. In mid winter to early spring clusters of pink buds open to pendant urn shaped white flowers. Loved by over wintering Anna’s hummingbirds. A low and spreading Manzanita to 4′ tall by 6′ wide in 7 years. Not as rapid of growth as other varieties. Full sun and average, well drained soil. Do not amend the soil  but rely on our own native soils perfect fertility. To further enhance success double dig a wide area around the plants new home. This incorporates oxygen into the soil in a wide area and also allows the percolation of water. Mulch after planting with a coarse bark. Very pretty, very gray dome shaped shrub which eventually reveals contrasting mahogany glossy peeling trunks. A very pretty species that is uncommon in Oregon but whose range extends south all the way to Baja Norte. Once established, do not water- neglect and perfect climate adaptation will do the rest. Oregon native plant.

Arctostaphylos 'Greensphere'

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. Very slow growing.
