Spreads by root suckers to form large colonies in the wild. All of the trees in a colony may rise from the same parent. Dioecious (separate male and female trees). Attractive, greenish-yellow flowers appear in clusters at the branch ends in spring. Flowers on female trees (if pollinated) give way to small pendant clusters of bluish-black berries (drupes) which are borne in scarlet cup-like receptacles on scarlet stalks (pedicils).
