Oregon Grape
Black Crowberry

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.

Black Crowberry is a native evergreen shrub that forms low, spreading mats. It has unique foliage that spiral around the stem, and small dark berries, giving it visual appeal. The berries are edible, but can be acidic, so are not generally eaten fresh. In colder climates they have a sweet, tart taste, and are dried, used in deserts, or for making jams or jellies.
It provides food for birds and mammals, while its flowers attract pollinators such as bees. Its ability to grow in harsh climates makes it an important species for ecological balance.
Black Crowberry has historical significance as it provided a vital food source for the indigenous cultures of the arctic regions. It is abundant in Scandinavia and is used to make liqueurs, wines, and juices. In Newfoundland and Labrador the berries are known locally as ‘blackberries’ and are used in jams, jellies and baked goods like buns and puddings.
