Grouseberry
Oregon Grape

Grouseberry is a native, low-growing deciduous shrub known for its edible red berries. In early summer, it produces small, urn-shaped flowers ranging from white to pink that attract bees and other pollinators. The berries provide an important food source for many types of wildlife, including game birds such as grouse, which gives the plant its common name. People can also enjoy the berries fresh or in baked goods, though they can be difficult to harvest in large quantities.

Spreading by rhizomes, Grouseberry forms dense, broom-like mats that help stabilize soil and prevent erosion, while also providing cover for ground-nesting wildlife. It is commonly found beneath conifers in open forests, subalpine meadows, and occasionally on rocky slopes in mountainous regions. It is well-suited for naturalization, ecological restoration, and soil stabilization projects.

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.
