Comments: Red-osier Dogwood is a high elevation, high water use species found in Arizona’s Sonoran Desert Sky Islands and other riparian areas above 5,000 feet. Cornus sericea is definitely not a desert species. The variety found in Arizona is Cornus sericea var. sericea the species more widespread across the United States and Canada. Sericea is Latin for “silky” which is a reference to the silk texture of the leaves. It readily spreads along creeks through underground stolons and forms thickets along the creek and in riparian areas.

Red-osier has been used as a cold remedy and cough medicine by Native Americans. See ethno-botanical uses at Native American Ethnobotany, University of Michigan, Dearborn.

There is also a Native American use listing for Red-osier Dogwood in the Native Plants Journal, Native Plants Journal Network, for Cornus sericea ssp. sericea
