A deciduous, multi-stemmed shrub, reaching 6 feet tall and 4 to 6 feet wide. Widely distributed through western North America at a variety of sites, grows best with good sun light. Bright yellow flowers bloom in April, some flowers have a slight reddish purple tinge. Yellow-green foliage makes this an ornamental shrub even in the fall. Important for conservation as it produces small berries that attract wildlife and stabilizes the soil for both upland sites and damp areas.
