Flowers in tight clusters, capitate, subtended by four large, white, petal-like sepals. Fruit a drupe, red, glossy, ripening in fall, several to a cluster. Flower buds form in the fall and are often present with the fruits as the leaves change.   

Notes

Flowers late April to early June

Wetland indicator: Facultative Upland -

Probably the most widely planted small tree, its popularity has waned somewhat due to several problematic diseases. Such is the case with many popular landscape trees and shrubs. Flowers are large and showy. Fall color is often a brilliant red or purple-red. There are several cultivars with pink sepals. Dirr cautions that cultivars should be selected for cold hardiness in colder zones. The wood is extremely dense and hard.
