Cotinus coggygria 'Royal Purple'

Previously known as:

  • C. coggygria 'Kromhout'
Description

The award-winning 'Royal Purple' Smoketree is a large shrub or small tree with a compact growth habit and showy purple leaves.  It was introduced into the United States in 1953, originating in Boskoop, Holland. 

The tiny flowers that appear on 6" to 8" long panicles are insignificant, however, Royal Purple has the signature smoketree plumes of billowy hairs that follow the blooming.  They are attached to the elongated stalks of the spent flower clusters.  The hairs are pink to purplish pink and appear as fluffy puffs.  The colors and texture giving an appearance of smoke.  

Planting in a location that provides full sun will lead to the best leaf coloration.   Evenly moist, well-drained soil is preferred.  It will not tolerate overly wet soils.  A layer of mulch will help retain moisture.  Once established, the plant will be drought tolerant.  

Pruning can be accomplished in late winter to early spring.  Cutting back hard will promote the growth of new shoots, however, will sacrifice flowering.  

Mass plant it or plant in small groups in a shrub border.  Its striking leaves and spent flowers make it an excellent choice for a specimen or accent plant.  It works well to screen or it can be pruned into a hedge.

Insects, Diseases, and Other Plant Problems:  Relatively pest and disease free, leaf spot, verticillium wilt and rust can appear.
