Noteworthy Characteristics

Cornus kousa, commonly called Kousa dogwood, is a small, deciduous flowering tree or multi-stemmed shrub that typically grows 15-30’ tall, with a vase-shaped habit in the early years but eventually maturing to a more rounded form. Bloom occurs in late spring. The showy parts of the Kousa dogwood “flower” (3-5” across) are the four narrowly pointed petal-like white bracts which surround the center cluster of insignificant, yellowish-green, true flowers. Flowers are followed by berry-like fruits (to 1” diameter) which mature to a pinkish red in summer and persist into fall. Fruits are technically edible, but are usually left for the birds. Oval, pointed leaves (to 4” long) are dark green.

Problems

No serious insect or disease problems. This plant has better disease resistance and better cold hardiness than flowering dogwood, and is an excellent alternative to flowering dogwood in areas where dogwood anthracnose is a problem.

Garden Uses

A stunning flowering tree or large shrub with good fall color. Plant as a specimen or in small groupings on residential property around homes, near patios or in lawns. Also effective in shrub borders, woodland gardens, bird gardens or naturalized areas.
