Cotinus obovatus, commonly called American smoketree, is a small, deciduous, rounded, Missouri native tree or large, upright shrub that typically grows 20 to 30 feet tall and occurs in limestone glades, rocky limestone bluffs, and bald knobs in the area of southeast Missouri. Smoketree gets its common name, not from the 6- to 10-inch flower clusters (tiny, insignificant, dioecious, yellowish-green flowers) which bloom in June, but from the billowy hairs attached to elongated stalks on the spent flower clusters, which turn a smoky pink to purplish-pink in summer, thus covering the tree with fluffy, hazy, smoke-like puffs. Bluish-green leaves are, as the species name suggests, obovate. Foliage turns a variety of colors in the fall, including yellow, red, orange, and reddish purple, producing some of the best fall color of any native American trees and shrubs. It is not subject to serious insect or disease problems, but it can be susceptible to leaf spots, rust, and wilt.
