Plant advice from The Morton Arboretum: A native plant to the Midwest. Staghorn sumac is often used in mass plantings, for naturalizing, or on steep slopes. Its open habit and hairy stems resemble horns on a male deer, giving staghorn sumac its name. It is one of the last plants to leaf out in the spring with bright green leaves that change to an attractive yellow, orange, and scarlet in fall. Among the most recognizable characteristics are large, upright clusters of fuzzy red fruits that appear above the branches in late summer on female plants. They are highly appealing to birds.
