Redosier dogwood is a native species that is most common in the northern latitudes of North America [116,200] but ranges widely from Alaska and northern Canada as far south as Virginia, southern California, and Chihuahua, Mexico [36,76,196,230,255]. In its more southern range, redosier dogwood is largely restricted to riparian areas and other moist sites [62,205,332] and is thought to be limited by high temperatures . Cornus sericea subsp. occidentalis is restricted to the western states of Alaska, Washington, Oregon, California, Montana, and Idaho, while Cornus sericea subsp. sericea occurs throughout the redosier dogwood range . For local distribution information, consult the county-level maps available at the PLANTS Database.
