Grouseberry

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.

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.
