Cornus kousa (Kousa Dogwood) is a small, deciduous flowering tree or multi-stemmed shrub with 4 seasons of interest. In spring, a heavenly array of star-like blooms appear. They consist of four narrowly pointed white bracts which surround the center cluster of tiny yellowish-green flowers. The blossoms give way to pinkish-red to red fruits in summer, which persist into fall, unless devoured by hungry birds. In summer, its canopy of layered branches, clad with oval, pointed, dark green leaves, provides shade and beauty. In the fall, it offers spectacular bright red color when its foliage turns attractive shades of purple and scarlet. In winter, its exfoliating, mottled, tan, and gray bark adds interest to the landscape.
Hardier and more disease resistant than Cornus florida, Cornus kousa is an excellent alternative to flowering dogwoods.
