Cotinus obovatus Raf.
Cotinus americanus Nutt.
The American smoketree is a North American native.
Identification: American smoketree takes the form of a large shrub or small tree reaching 15-30' (4.6-9.1 m) in height, and about the same width. The bark is gray-brown in color, and flaky, and the sap has a strong odor. The wood is a deep orange-yellow color. Leaves are bluish-green, 2-5" (5-12 cm) long × 1-2½" (2.5-6.3 cm) wide. Leaves are yellow, orange, red, or purple in the fall. Flowers are panicles (groups) 6-10" (15-25 cm) long, composed of many long, thin reddish or purplish petioles (stems that support the flowers). Each petiole is tipped with green to greenish-white flowers. The flowers are inconspicuous, but the color of the petioles is visible from a distance as a smoky, purplish haze—thus the tree’s common name.
