Restoration and Conservation

Snowberry is a valuable plant to many types of animals in the Pacific Northwest. As a flower, the nectar is a useful food source to many bees, insects, and pollinators, including the Anna’s and rufous hummingbirds. The berries, which last into the winter, are eaten by birds like towhees, thrushes, robins, grosbeaks, and waxwings. The thickets and shrubs provide cover for small birds to hide in. Birds aside, the sphinx moth (Sphinx vashti) uses snowberry as it’s only food source in larval stage in the Pacific Northwest.

Ethnobotany

The snowberry shrub has been an important medicinal and household plant to many Naive Americans. Snowberry contains saponins, a naturally soapy substance useful for treating and cleansing the skin. Snowberry was used to kill body parasites, clean and heal wounds, used as an eye wash for sore eyes, and as a diluted tonic, used as a gentle cleanser for babies and children. The Chehalis Tribe is documented for using the berries to wash hair.
