Restoration and Conservation Applications
Red osier-dogwood is an excellent plant for restoration purposes. It is easy to propagate, grows quickly, and has wildlife value. It does well in areas that are seasonally inundated with water. Places along stream banks and shorelines are ideal. It has a fibrous root system which is great for soil stabilization. This dogwood is an excellent shrub to plant along sunny edges and in deciduous canopy shade because it is sun-loving and shade tolerant. It provides ample shade on the ground below and nearby, which is serves well to shade out weedy species like reed canarygrass and Himalayan blackberry. The flowers in spring provide nectar for insects and hummingbirds. Birds eat the berries that develop in summer and early fall, as well as nest in the protective shrub cover.
The beautiful slender red stems are used for basket weaving by Native American tribes. The twigs were used for all sorts of functions including salmon spreaders and medicinal uses. On the west coast, native tribes made tea from the bark for medicinal purposes. Parts of the plant were used by native tribes to produce black, red, and khacki dyes. Berries were also dried and eaten.
