Vine maple (Acer circinatum) commonly grows as a large open shrub or small tree reaching 10-25 feet tall. It typically grows in the shady forest understory but is sometimes found out in the open. Like many plants, it typically gets taller in the shade and stays more compact in the sun.

Like all maples, the branches and leaves grow in pairs off the stem, known as “opposite branching.” Leaves are 3-14 cm long and broad, and thinly hairy on the underside. They are palmately lobed with 7-11 lobes, which are pointed with coarsely toothed margins. The flowers make a small but dramatic show in spring, blooming a bright red and whitish-green from May – June. The fruit is a two-seeded winged fruit called a samara, starting green then turning reddish-brown as they ripen. The leaves turn bright yellow to orange-red in fall and provide some of our most vivid native fall color.

Vine maples are important trees for wildlife. They provide nesting sites and cover for many birds and mammals. Vireos weave basket-like nests that hang in the forks of the branches. Birds use the seed stalks and leaves for nest building. Squirrels, chipmunks and birds eat the seeds, and the caterpillars of the brown tissue moth and Polyphemus moth forage on the leaves.

Vine maple grows best in part shade and moist soils. It can live out in the open but exposed leaves may burn and turn reddish in the afternoon sun. This is a beautiful specimen plant for a shady corner, or a tall screen to soften the side of a house. Pair it with snowberry and ferns for year-round interest.

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 plant grows large, but annual pruning will keep it right-sized and encourage red twig growth.

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.

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.

Osoberry is a fast-growing, multi-stemmed shrub to small tree with reddish to purplish-brown bark. In open sunny locations it may form a dense shrub, while in the shade it becomes more open to sprawling. This is one of our earliest flowering native shrubs, and its slender, lime-green leaves are one of the first signs that spring is on the way!

This woodland plant does best in moist areas with dappled shade, and can tolerate many soil types, including heavy clay.

In the early spring, both male and female osoberries produce dangling clumps of whitish flowers. Female plants will then produce small hard berries towards the end of summer (male plants produce no fruit). The fruit is peach-colored early in the season, maturing to blue-black in the fall, and is a favorite of many birds and small mammals. Osoberry also serves as a host for several caterpillar species, and the flowers are a source of nectar for butterflies, hummingbirds, and pollinators, making this an excellent wildlife plant.

Blue elderberry (Sambucus cerulea) is a large, fast-growing deciduous shrub or small tree featuring showy clusters of creamy-white flowers that mature into large clusters of blue-black berries.

This shrub is a great addition to your wildlife garden. Many birds eat the berries, and butterflies visit the flowers for nectar. The plant provides food for the young of spring azure butterflies and various moths. Native solitary bees shelter and lay their eggs in the hollow twigs. Dead elder wood is also the preferred habitat of the mushroom Auricularia auricula-judae, also known as Judas’ ear fungus or wood ear fungus.

Blue elderberry can get quite tall, reaching up to 15 feet in height. Plant it in sun to part shade in well drained soils.
