[Wikipedia] Description, Distribution: The branches have fine hairs and the young bark is thin and smooth, becoming scale-like with ridges as it ages. The leaves are opposite, simple, oval. They turn orange to purplish in autumn. The flowers commonly bloom twice per season, once in the spring and again in late summer or early fall. The fruit is a compound pink-red or orange drupe about 1 to 1.5 cm. long, in clusters containing 20 to 40 drupelets, each of which contains two seeds. They appear in September or October.
