Shrub/Tree Cotinus coggygria [Common Smokebush] Usually dioecious, so heavy-fruiting clonal material should be used when possible. Can be pruned to low framework each year to promote plant coloration which occurs best on vigorous stems. Misty fruiting panicles give the species its name. The fine-textured hairs on the fruit pedicels and peduncles change colors, being best when tinted smoky pink.
