Oregon Grape
American Black Currant

Oregon Grape is an evergreen shrub native to North America, found along the Pacific coast. In spring, the bright golden-yellow flowers appear in clusters above the leaves. These flowers eventually give way to edible blue berries in late summer. While not a true grape, the berries appear grape-like due to their colouring and clustered growth. They can be eaten fresh, but the sour taste and high amounts of natural pectin make them well suited for preserves.

The Oregon Grape has leaves that are glossy, leathery, and spiny-edged. This feature gives it its alternate name of Holly-leaved Barberry. When the leaves emerge in the spring they are a bronze-red colour. In the summer they transition to green, followed by bright red to deep burgundy in the fall. Leaves are retained throughout the winter and colder temperatures cause the leaves to turn purplish bronze, providing year round interest to the landscape.

American Black Currant is a native deciduous shrub known for its clusters of small black berries that ripen in mid-to-late summer. The berries are edible and have long been used for fresh eating, preserves, and baking. They provide food for birds and mammals, and their fragrant spring flowers attract bees and other pollinators.

American Black Currant’s foliage serves as a host plant for butterfly species such as the Green Comma and Gray Comma, and its dense branching offers cover for wildlife. The shrub has traditionally been planted in shelterbelts, riparian buffers, and restoration projects.
