Like other Cornus, it has opposite, simple leaves, 4–10 cm long. The tree is extremely showy when in bloom, but what appear to be four, white petals are actually four spreading bracts below the cluster of inconspicuous yellow-green flowers. The blossoms appear in late spring, weeks after the tree leafs out.  It can be distinguished from the flowering dogwood (Cornus florida) of eastern North America by its more upright habit, flowering about a month later, and by the pointed rather than rounded flower bracts.  The Kousa Dogwood is beautiful flowering tree with good fall color.
