Overview

The American Smoketree (Cotinus obovatus), also known as Chittamwood, Wild Smoke Tree, or Yellow Wood, is a rare and enchanting native gem of the south-central United States. Found on limestone bluffs and rocky slopes from Tennessee to Texas, this small deciduous tree or large shrub offers a magical display that belies its tough, drought-tolerant nature.

The "Smoke" Spectacle

The tree's name comes from its extraordinary early-summer floral display. The actual flowers are tiny and inconspicuous, but the sterile flower stalks elongate into fine, silky hairs that persist for weeks, enveloping the canopy in a gauzy, pinkish-purple to smoky-gray haze. Backlit by morning or evening sun, the effect is ethereal—a cloud of color suspended among the branches.

Foliage & Form

The leaves are a standout feature: obovate (egg-shaped, wider at the tip), 3–5 inches long, emerging with a reddish tint, maturing to a rich, lustrous blue-green. Autumn brings a spectacular second act: foliage ignites in brilliant shades of orange, red, purple, and yellow—often all on the same leaf. The bark on older trunks is gray-brown and scaly; the wood is a vibrant, deep orange-yellow (hence "Yellow Wood"), historically used for dye.

Culture & Uses

Hardy in USDA Zones 4–8, American Smoketree thrives in full sun to part shade and well-drained, even rocky or alkaline soils. It is exceptionally drought-tolerant once established, making it ideal for xeriscaping, naturalistic plantings, and difficult sites. Slow to moderate growth (15–30 ft tall/wide) suits small gardens. It is generally pest-free and deer-resistant. A superb specimen for multi-season interest: spring flowers, summer "smoke," fall fireworks, and winter architecture.
