Japanese Kousa Dogwood

Cornus kousa
This dogwood is native to Japan, Korea, and China and is often called by its native country name.  It can be classified as a small tree (15 to 30 ft. tall) or a large bush. The Kousa Dogwood is a good example of a four-season tree. In late spring small yellow flowers, which attract butterflies, are surrounded by showy whitepetal-shaped leaves (bracts). The flowers produce a bright pink or red fruit in the summer which attracts songbirds.  In the fall the leaves turn a brilliant scarlet purple color.  The exfoliating grey bark and interesting horizontal limb branching and tree formation add to its attractiveness in the winter. Of all the dogwoods it is the most disease resistant and is even somewhat deer "resistant". No wonder it is apopular landscape tree.
