Cotinus (/koʊˈtaɪnəs/[2]), the smoketree or smoke bush, is a genus of seven species of flowering plants in the family Anacardiaceae, closely related to the sumacs (Rhus).

The flowers are clustered in a large open terminal panicles 15–30 cm long with a fluffy grayish-buff appearance resembling a cloud of smoke over the plant, from which the name derives.

Rhus cotinoides) is native to the southeastern United States, from Tennessee south to Alabama and west to Oklahoma and eastern Texas.

It is a larger plant, frequently becoming a small tree between 3 and 5 meters (10 to 15 feet) tall, with a trunk from 20 to 35 centimeters (8 to 14 inches) in diameter.

Several bronze or purple-leaved cultivars of C. coggygria have been selected, with warm pink inflorescences set against purple-black foliage; the most common in commerce are 'Notcutt's Variety' and 'Royal Purple'.
