Kwanzan cherry has double-pink, beautiful flowers and is usually purchased and planted for this reason.

The upright-spreading form, reaching 15 to 25 feet tall, is quite attractive in many locations including near a patio or as a specimen away from lawn grass competition.

The tree makes beautiful flowers and is planted along with Yoshino cherry in Washington, D.C., and Macon, Georgia for their annual Cherry Blossom Festivals.

This cherry provides a strong contrast to lighter-colored cherry blossoms, like Yoshino cherry, by showing a pink flower later in April and May. It becomes a larger part of the cherry show as spring introduces flowering later in the Northeastern United States.

Neither stress-tolerant or highly drought-tolerant, Kwanzan cherry should be located on a site with loose soil and plenty of moisture. Not for an urban parking lot or exposed street tree planting where borers and other problems normally attack. It has some tolerance to salt and tolerates clay if well-drained.

Kwanzan cherry has good yellow fall color, does not bear fruit, but is somewhat troubled with pests. These pests include aphids which distort new growth, deposits of honeydew, and sooty mold. Bark borers can attack flowering cherries, and scale insects of several types can infest cherries. Spider mites can cause yellowing or stippling of leaves and tent caterpillars make large webbed nests in trees then eat the foliage.

Kwanzan cherry prefers full sun, is intolerant of poor drainage, and is easily transplanted. However, the useful life of the species is limited to about 15 to 25 years for 'Kwanzan' when on a good site. But it is an enjoyable tree and worth planting.
