Oregon Grape
Bilberry

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.

Bilberry is a native perennial shrub valued for its small, blue-black berries that ripen in mid to late summer. The berries resemble blueberries but have a richer, more tart, and intense flavor. They have long been used for fresh eating, baking, and preserves, while also providing food for birds and mammals. In spring, its delicate pinkish flowers attract bees and other pollinators.

Growing low to the ground, Bilberry forms spreading colonies that create dense understory cover. This growth habit provides food and shelter for wildlife, and its foliage adds seasonal interest by turning red to purple in autumn. With its adaptability and ecological benefits, Bilberry is well-suited for naturalization, ecological restoration, and pollinator gardens.
