Oregon Grape
Northern 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.

Northern Black Currant is a native deciduous shrub found across Canada and the northern United States. Dark purple to black berries that ripen in summer and provide food for wildlife and humans. Fragrant yellow-green flowers that attract a wide variety of pollinators.
This shrub is well adapted to moist soils and can even survive periods of flooding. It has an interesting bronze colour in fall.
