Cotinus Coggyrgria 'Royal Purple' is an upright, loose-spreading, multi-stemmed, deciduous shrub that is native from southern Europe to central China. It gets its common name of smoketree (or smokebush) not from the tiny, insignificant, yellowish flowers which appear in branching, but from the billowy hairs (attached to elongated stalks on the spent flower clusters) which turn a smokey pink to purplish pink in summer, thus covering the tree with fluffy, hazy, smoke-like puffs throughout summer.
