Snowberry grows in shady and moist mountain and forest habitat, in woodlands and on floodplains and riverbanks. It can grow in a wide variety of habitat types.

This shrub is used for erosion control in riparian areas, and it is planted in ecological restoration projects on disturbed sites such as abandoned mines. Its white fruits make it popular as an ornamental plant.

Snowberry is an important food source for a number of animals, including bighorn sheep, white-tailed deer, and grizzly bears. Many birds and small mammals use it for food and cover.
