Oregon Grape
Bristly 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.

Bristly Black Currant is a native deciduous shrub that grows in moist forests, swamps, and riparian areas. In summer, it produces clusters of dark purple to black berries that provide food for wildlife, while its reddish-purple flowers attract pollinators. The berries are technically edible and enjoyed by some, but many find them unpleasant and bitter.

Thriving in moist soils and shaded locations, Bristly Black Currant helps stabilize soil and supports diverse habitats. It is valuable for conservation plantings, wetland restoration, riparian buffers, and naturalization projects.

Note: When crushed, the berries are known to release an offensive odour.
