- Description
-
Chinese Catalpa is a small deciduous tree native to China's forests. It self-seeds easily and has naturalized in some areas of the U.S.A. In its mature form it can be an attractive rounded shade tree but it often grows out of shape and its large leaves can become damaged as the growing season progresses making them less attractive. It is an ideal tree for that tricky low wet spot or an area with poor soils. It prefers moist loamy soil high in organic matter and full sun to partial shade.
Insects, Diseases, and Other Plant Problems: No serious problems. Catalpa sphinx moth caterpillars can do significant damage. Mildew, twig blight, verticillium wilt, and leaf spots are occasional problems. Leaves can become damaged and look ratty from wind or hail.
