Cornus alternifolia
pagoda dogwood
A large, deciduous shrub or small, graceful tree with an arching habit up to 6m in height. Glossy, purple-green stems hold alternate, dark green, ovate leaves that turn a deep purple burgundy-red in autumn. From late spring to summer, lacy white, lightly fragrant flower heads are held above the leaves. Dark blue fruits follow in summer and are soon taken by birds.
