Perennial, understory shrub with compound pinnate leaves. Leaves are evergreen, and have spiky serrations. Spherical yellow blossoms appear in spring, forming blue berries in summer. Native Americans used it for many medicinal and ceremonial purposes, and today roots, leaves and berries are marketed for their medicinal properties. This is the Oregon State Plant.
