Amelanchier alnifolia

Serviceberry (Amelanchier alnifolia) is a large shrub or small tree, growing 6-18′ tall and up to 10′ wide. Leaves are round to oval, 1-2 inches long, and pale green in color. Once it is several years old, serviceberry starts blooming with fragrant white flowers from mid-spring to early summer followed by small, dark blue, edible fruit. Leaves turn a delicate yellow in fall.

This attractive shrub is also great for wildlife. Birds and small mammals eat the tasty fruit. Pale swallowtail and Lorquin’s admiral butterflies lay their eggs on serviceberry, and in winter many species browse the twigs and bark.

Serviceberry is a common and widespread species, growing native from Alaska to California, and across Great Plains into eastern Canada. It grows in full sun to partial shade, and tolerates dry, moist, or wet soil. Shrubs in sunnier sites tend to have the most vibrant fall color.

Sambucus racemosa

Red elderberry (Sambucus racemosa) is a large shrub or small tree, growing up to 20’ tall by 20’ wide. It grows in full sun to full shade, and prefers moist to wet soil. It is deciduous with large, compound leaves. White flowers bloom from early-spring to mid summer in 1.5”-3” upright, pyramid-shaped clusters.

This shrub provides food and shelter for many wildlife species. Birds, mammals, and insects eat all parts of the plant including the leaves, bark, roots, and bright red fruit. The spring azure butterfly lays its eggs on red elderberry and the hollow stems provide nest space and overwintering shelter for solitary bees. This plant also supports beneficial insects that eat garden pests.

Prunus virginiana

Chokecherry (Prunus virginiana) is a deciduous, thicket-forming shrub or small tree commonly found across much of the United States. Varieties native to Oregon include black (var. melanocarpa) and western (var. demissa) chokecherries.

This small, elegant tree can grow anywhere from 12-40 feet tall. It has dangling clusters of small, fragrant flowers in spring to mid summer. The leaves are oval, serrated, 2-4 inches long and pointed at the tip. The fruit is a ¼-½ inch cherry that starts red and becomes purple or black when ripe. Fall foliage is yellow.

Chokecherry is a very valuable tree for wildlife. Many butterflies rely on it for nectar, such as the pale swallowtail, silvery blue, spring azure, and painted lady. Lorquin’s admiral and spring azure butterflies lay their eggs on chokecherries.

Crataegus douglasii

Black Hawthorn (Crataegus douglasii) is a deciduous, thicket-forming shrub or small tree that grows anywhere from 20-40 feet tall. It is a common plant in Oregon and Washington on both sides of the Cascades, growing in moist, well-drained soils. The black hawthorn is an important species for wildlife, attracting pollinators and providing protected nesting and edible fruits for birds and other small wildlife.

Leaves are 1.5-3 inches long and up to 1.5 inches wide, doubly serrate, ovate, and sometimes lobed. Small white flowers bloom in clusters from late spring to early summer. The small, oval fruits are purple-black when ripe, one quarter to a half inch in size. This attractive tree turns yellow, orange, and red in fall.

Black hawthorn is an important species for wildlife, providing protected nesting and edible fruits for birds and other small wildlife. The young of gray hairstreak and mourning cloak butterflies feed on black hawthorn, and the flowers attract many native bees.

Viburnum ellipticum

Oval-leaved viburnum (Viburnum ellipticum) is a deciduous shrub that brings three-season interest to any native garden. Clusters of small white flowers bloom in late spring and early summer. The berry-like fruit is red at first, becoming black when ripe. The simple oval leaves are 1-3″ long, coarsely toothed, and turn red in the autumn before dropping to reveal straight, upright central stems and widely spaced, horizontal branches.

This shrub supports pollinators and beneficial insects. Many birds and small mammals eat the berries, and birds nest and shelter in its branches.

Oval-leaved viburnum is native west of the Cascades in Oregon and Washington, where it is found mainly in dry open woods and lowland thickets. This shrub tolerates both seasonal flooding and drought, making it a hardy addition to the landscape. It does well as a border plant, such as at the edge of a wooded area. Pair it with snowberry, salal, and low Oregon grape for year-round beauty!

Cornus sericea

Red osier dogwood (Cornus sericea) is a medium to tall deciduous shrub. It can grow 6-15 feet tall and 5-10 feet wide depending on site conditions, and spreads to form dense thickets. It is attractive year round with red winter twigs (especially in sunny sites), creamy-white flower clusters, red to purple fall color, and bluish-green to white fruits.

This shrub is excellent for wildlife. Painted lady butterflies visit the flowers for nectar, and spring azure butterflies lay their eggs on the newly developing leaves and buds. Dozens of species of birds and mammals rely on it for food year-round, eating the new shoots in the spring, berries in summer and fall, and twigs through the winter. Birds take cover and nest in the shrubs, and even some amphibians lay more eggs in wetlands with red osier dogwoods than without.

Cuttings readily root, and it is an excellent shrub for improving the health of stream banks and wetlands. In the wild, it commonly grows in wetlands and other habitats with damp soil.

Frangula purshiana

Cascara (Frangula purshiana) is found along the Pacific coast from British Columbia to northern California along riverbanks and in other moist locations.

A hardy, compact, attractive tree, it is often planted in Portland’s parking strips. In the spring it produces clusters of small, green-white flowers. In late autumn, the leaves turn a delicate yellow and persist through many a winter storm.

The flowers attract many pollinators in early summer such as Lorquin’s admiral butterflies. Pale swallowtail butterflies lay their eggs on the leaves. Birds enjoy the fruit, but they are toxic to humans and should be avoided.
