American smoketree is an upright, small tree or multi-trunked shrub, growing 15-30 ft. tall. Has a short trunk, open crown of spreading branches, resinous sap with a strong odor, and deep orange-yellow heartwood. Six to ten inch flower panicles develop long, red or purple, hairlike petioles that, in the crowded flower clusters, create a smoky appearance. (The flower itself is small and not showy.) Berries occur infrequently on pinkish stems; these also have a smoke-like look. Spring leaves are silky pink, becoming bluish to dark green. Fall leaves are magnificently colorful. A gnarled limb structure and the dark, flaking bark are other attributes. The masses of smoke-like fruit clusters with hairy stalks of sterile flowers give the species its common name.

Native to rocky, usually mountain soils from Kentucky, Tennessee, and northern Alabama west to Oklahoma, with disjunct populations in a few counties of central Texas, Cotinus obovatus is an outstanding small, ornamental tree. Its bark is decorative, its leaves are soothing blue-green in spring and summer and flaming oranges and reds in fall, and its flowers form ethereal clouds of pink and purple in spring. The floral panicles wave in the breeze, giving the illusion of clouds of smoke. It is drought-tolerant, disease-resistant, well-adapted to the stony soils of its native habitat, and should not be over-watered or over-fertilized.
