![]() Smoke bush can tolerate in a wide variety of conditions including lean, rocky soils. To train into a small tree, cut out all but one or more of the main trunks and limb up the side shoots. While this will control the plant’s size and create a unique ornamental effect, blooms will be sacrificed. This will promote new vertical shoots with larger leaves and enhanced foliage coloration. ![]() ![]() Plants can also be kept smaller by cutting them back hard to the ground. Since smoke bush blooms on the previous year’s growth, hold off on any major pruning until after summer flowering. In late winter or early spring, cut out dead, diseased and crossing branches, and lightly shape as needed. Larger varieties can also be trained into small trees. Plants can be allowed to reach their natural shape and size, kept to a smaller size, or shaped as hedging. Refrain from pruning for the first few years, as it can take that long for young specimens to bloom. coggygria), which comprises most ornamental varieties, is indigenous to Europe and parts of Asia. American smoke tree ( Cotinus obovatus) is native to the southern US.Types:Īlso known as smoke tree, or smoke bush tree, this member of the sumac family includes two species: Fall color is red, yellow, orange, purple, or coral. Panicles occur in shades of cream, pink, mauve, or purple that shift in color as they age. The puffy spent blooms, which resemble cotton candy, can reach 12 inches long. Tiny yellow or cream flowers appear in spring showy panicles which develop into even showier puffs with a hazy, smoke-like appearance that last for several months. This deciduous woody shrub or small tree has dense, multi-stemmed branching, with green, purple, or gold leaves. Exposure:įull sun to partial shade bloom and foliage color is best with at least six hours of direct sunlight. coggygria 'Kromhout'.Upright bushy or open habit, 4 to 30 feet tall and 4 to 25 feet wide, depending on variety. 'Royal Purple' was raised at Lombarts Nursery in Boskoop, Holland. Cotinus is in the same family as and closely related to the sumacs ( Rhus). Foliage retains good color without much fading throughout the growing season. Ovate to obovate leaves (to 3” long) emerge a rich maroon red in spring, and then gradually mature to dark purplish-red to purplish-black in summer. 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. It gets its common name of smoketree (or smokebush) not from the tiny, insignificant, yellowish flowers which appear in branching, terminal panicles (to 6-8” long) in spring, 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. It typically matures over time to 10-15’ tall and as wide. Cotinus coggygria, commonly known as smoketree, is an upright, loose-spreading, multi-stemmed, deciduous shrub that is native from southern Europe to central China.
