The fluffy pink plumes in summer really do look like clouds of smoke.

But it is the foliage that particularly distinguishes 'Royal Purple'. As is the case with all plants of this species, it gets its common name of smoketree (or smokebush) not from the tiny, insignificant, yellowish flowers which appear in branching, terminal panicles (6-8” long) in spring, but from the billowy hairs (attached to elongated stalks on the spent flower clusters) which turn a smoky pink to purplish pink in late spring, thus covering the plant with fluffy, hazy, smoke-like puffs throughout summer. It is a deciduous, upright, loose-spreading, multi-stemmed shrub that typically matures over time to 10-15' tall. ‘Royal Purple’ is a compact, purple-leaved version of the European species. Specific epithet comes from the Greek word kokkugia meaning smoke tree. Genus name comes from the Greek word kotinus meaning olive. Fall color is highly variable, but at its best produces attractive shades of yellow, orange, and purplish-red. Bluish green leaves (to 3” long) are ovate to obovate.

Cotinus coggygria, commonly known as smoketree, is an upright, loose-spreading, multi-stemmed, deciduous shrub that is native from southern Europe to central China. Pruning a smoke tree to encourage a bushy shrub: Hard prune the shrub back to 6 to 8 (15 20 cm) above the ground during the first two years after planting.
