Clackamas Iris is a rare endemic to only three counties in northern Oregon. Though it appears in scale with Pacific Coast Iris, it is not related and is more closely aligned with bearded Iris. Pale green 15mm wide leaves first emerge vertically before settling to a more horizontal position. Light lavender buds unfurl to white with yellow on the falls in May-July. In its native range this smaller iris is everywhere which  begs the question; Why isn’t its natural range larger? Not bothered by deer or pests this is a supremely climate adapted perennial. To 12″ tall in bloom the arching leaves equal that and spreads out. Light consistent summer water to establish, then only what falls from the sky. Full sun to quite a bit of shade. In habitat it is an understory component with Sword Ferns and shrubs such as Hazel, Oso Berry, and Viburnum. Provide deep rich soil and room to spread. This Iris makes very large colonies quickly- to 3′ wide.  The broad leaves are winter deciduous. Wonderful Iris for gardens and wild areas.  Oregon native plant.

Dicentra formosa

Oregon bleeding heart is a widespread lush, long blooming perennial wildflower for moist conditions in shade to full sun. A somewhat rambunctious plant that spreads quickly by stolons. Do not plant it near shy or small plants that can become swamped. It tolerates quite a bit of shade and if in full sun it thrives with supplemental water and a massive flower display. Divided soft green foliage is very good looking, in April-July a continuous supply of rose colored downward pointing clumps of flowers on an 18″ spike. The foliage rises on average to half that height. Responds vigorously to amended soils and regular irrigation. In hot dry situations it will go quickly summer dormant. In the shade with water leaves persist to autumn and re-bloom  occurs. Not bothered by pests, including deer and snails and slugs. Frequently found in shady ditches in the Willamette Valley. Winter deciduous, if not already summer drought deciduous. An easy to grow, self sufficient perennial for wild areas. Mix with other vigorous and scaled plants. Very easy to grow.  Oregon native plant

A widespread perennial in the Pacific Northwest. There are two subspecies and this larger leaf form is the more common of the two. A mounding deciduous perennial for moisture retentive soils in light shade to shade. This perennial is often seen along creek banks and seeps where access to water is not very far away. In May-July 18″ spikes of clear starry white flowers crowd a vertical stem. Very pretty and light. An excellent native perennial for woodlands, stream banks. riparian areas. Spreads in rich soil to form extensive colonies foliage tops out at 8″. Excellent combined with native and non-native ferns. Very dark green leaves are handsome throughout the season on a tough and easy to grow plant. Fall color is red and orange before leaves go away. AKA Trifoliate Foam Flower, Northwest Foam Flower. Not bothered by disease or pests that includes snails and slugs. YAY. Oregon native plant

Frangula (Rhamnus) purshiana

AKA Cascara or Cascara sagrada. This is a widespread small tree to shrub in the northwestern part of the United states. West of the Cascades  its found in almost every biome. It can be a wind contorted shrub on blasting headlands at the coast. In the Willamette Valley its common where birds drop the berries/seeds on fence rows. Its even found in the Bitteroot mountains in Montana/Idaho. It was frequently used by indigenous people as a laxative. Cascara is a small round crowned tree/shrub. In drier locations it is more shrub like but in deep, rich soil with access to water it can grow to be a thirty five foot tree. Large round alternate leaves turn dark green and glossy in summer. In May and June the tiny greenish flower appear and transform into red fruits by autumn. This is the mechanism that makes this plant so widespread, its dispersal by birds. A lovely little straight trunked shade tree that requires almost no water once established. It functions as an understory component as well. Full sun to quite a bit of shade, including dry shade. Easy to grow and climate adapted. Average life span 35 years. In winter its very symmetrical open branch structure is handsome. Fall color is soft yellow to chartreuse and not especially showy.

Geranium tuberosum ‘Slender Silver Leaf Form’

This is a really pretty take on the more common form of Geranium tuberosum.  Rather than brilliant deep purple flowers this very distinct variety makes due with the hues pink and lavender. The foliage on this spreading bulb is what really shines. Deeply incised palmate leaves are brushed with silver hairs. This pairs with the more pastel colors of the flowers in a very good way. Rich soil to average soil in part shade. Once established rely only on what falls from the sky. Bloom is 4-6 weeks April to early June and the flowers wave above 18″ stems. Vigorous and healthy and not bothered by any pests, that includes slugs and snails who will leave it strictly alone. Goes quickly dormant with summer heat- disappears entirely. Very easy and satisfying perennial to grow in Cottage gardens, spring borders, will flower gardens. Combine with spring ephemerals and bulbs. Sophisticated cultivar that improves the species.

We’ve met a lot of good gardeners and I’m always most amazed at peoples attention to detail. Good gardeners love detail. Mary De Noyer is a favorite customer and well known for her fastidious and beautiful garden. Several years ago Mary brought this seedling Podophyllum to us and asked that we grow it. Her only stipulation was that we name it ‘Audrey’.  Done! This is a remarkable perennial that we are proud to finally have a salable population. The large convex star fish shaped leaves are a glowing amber to madder red. Following the unufurlment and maturation of the leaves pendant dark wine red flowers appear on the leaf petiole- in this case the trunk. To 2′ tall a mature leaf can be more than 1 foot across. This probable hybrid May Apple is a bold and beautiful perennial for part shade to high overhead shade in rich soil with consistent summer moisture. Add all purpose fertilizer around the base each spring. For the first several years the clump of bold leaves increases close to a clump. After permanent establishment and with a lot of moisture this perennial will run by stolons. It will run as far as rich, moisture retentive soil allows. Beautiful plant. Thank you Mary De Noyer.

Tan bark oak or Tan Oak is native to the SW corner of Oregon south into the mountains of southern Calfiornia. The large convex leaves emerge clad in gray fur as this wears off it reveals a mature deep green with an underside of silver. Moderately fast growing evergreen tree to 45′ tall x 25′ wide in 30  years. Grows on average 2′-4′ per year when young. This close relative of Oaks produces acorns that are light tan and born out of an indumentum covered prickly cup. In Oregon this tree mostly of mountains can be found most extensively from Douglas and Coos County south to the coastal border. It is found in the higher elevations of the mountains of northern California where quite a bit of heavy wet snow occurs. This tree will bend in snow and ice and it will not break. Conical and spreading crown. Tan Oak which was harvested in the 19th and early 20th century for the collection of commercial tannins. Full sun, it grows well but is slower and a bit spindly as an understory tree. The furrowed bark is dark brown to black. Its range is almost the same in Oregon as Canyon live oak (Quercus chrysolepis) and cold hardiness is equivalent too, hardy just below 0ºF. Wonderful, stately, native evergreen shade tree. Ours are raised from acorns collected at the northern extent of its range in Douglas County.  Oregon native plant.

The O’Byrnes gave us this strain of the variegated form of Helleborus x sternii. Inheriting cold tolerance from H. corsica and nifty, thick palmate leaves from the more tender H. lividus .The result is a tough plant with green cupped flowers stained rose on the outside of the bell. The flowers remain effective for several months. Not quite as long as the straight H. x sternii, but a relatively long time. A shrubby species with large evergreen leaves. They are heavily speckled with cream dots with an underside to the leaves and the stems tinted pink. The palmate leaves become large and arching. Full sun with more frequent irrigation to full  shade with less. To 2′ x 2′. Deer and possibly rabbit resistant. The rough leaves resist weather. Site as you would for a small shrub. It is elegant with other woodlanders or can be grown with drought tolerant to low water plants even in full sun. Flower bend over enshrouded in a cup shape that protects the pollen from rain and the vagaries of winter weather.  Blooms January with flowers effective for three months. Great, sophisticated but tough plant for rural areas. May be afflicted with aphids in late spring. Hose those off or do not look closely.

Rubus parviflorus var. parviflorus

Western Thimble berry is a widespread relative of raspberries that grows in many biomes and is especially abundant west of the Cascades. The 5 petal pure white  flowers that arrive in spring are among the largest of any Rubus. Thimble berry also does not have thorns. YAY.  It forms imposing patches spreading by a creeping rhizome. The large maple shaped leaves can be up to 10 cm wide To 4′ tall and spreading – give it room and plan ahead. The sweet edible red berries appear in mid-late summer. They may be detached from a core on the end of the stem. It leaves a concave hollow berry- shaped like a thimble. Its fairly high in water content which means it does not ship well and its not big as a commercial crop. Nice looking large, opulent shrub for wild areas. Water to establish then none necessary in subsequent years. Thimble berry has a very long lifespan but it is also a seral species populating disturbed sites from fire, logging, roadsides. Full sun to quite a bit of shade with good air circulation- prone to powdery mildew in wet springs. It seldom causes permanent damage to the plant. Fall color is yellow to russet and lingers. Not bothered by deer  but birds will predate the fruit and then poop out a whole new colony. Wild areas, margins of forests.
