When brought into cultivation together, the two species will form hybrids some garden cultivars are of this parentage.Ĭultivation is best in dry, infertile soils, which keeps the growth habit more compact and also improves the autumn colour when planted in fertile soil, they become large, coarse and also tend to be short-lived, succumbing to verticillium wilt disease. coggygria have been selected, with warm pink inflorescences set against purple-black foliage the most common in commerce are 'Notcutt's Variety' and 'Royal Purple'. Several bronze or purple-leaved cultivars of C. The flower heads are usually sparser than in C. The foliage is described to be a red wine-like, and the shrub has deep pink flowers in the summer. The leaves are also larger, 6–13 cm long it also has varied but very bright fall color, usually brighter than the Eurasian species. It is a larger plant, frequently becoming a small tree between 3 and 5 meters (10 to 15 feet) tall, with a trunk from 20 to 35 centimeters (8 to 14 inches) in diameter. Rhus cotinoides) is native to the southeastern United States, from Tennessee south to Alabama and west to Oklahoma and eastern Texas. The American smoketree ( Cotinus obovatus, syn. Often classified in Rhus in the past, they are distinguished by the leaves being simple (not pinnate) and the 'smoke-like' fluffy flower heads. The fruit is a small drupe with a single seed. The flowers are clustered in a large open terminal panicles 15–30 cm long with a fluffy grayish-buff appearance resembling a cloud of smoke over the plant, from which the name derives. The leaves are deciduous, alternate, simple oval shape, 3–13 cm long.
They are large shrubs or small trees, native to the warm temperate Northern Hemisphere. Smoketree or smoke bush, is a genus of seven species of flowering plants in the family Anacardiaceae, closely related to the sumacs ( Rhus).
coggygria 'Kromhout'.Not to be confused with Cotinis, a genus of scarab beetles. '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. The Cotinus genus of smoketree is a group of flowering deciduous small trees or shrubs in the Anacardiaceae (sumac) family. 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. The only downside to planting this tree is that it has a short life span of less than a decade, writes Missouri Botanical Garden. As a hybrid of Prunus, it's resilient and produces vibrant, reddish-purple foliage under direct sunlight.
Specific epithet comes from the Greek word kokkugia meaning smoke tree. Purple-leaf sand cherry (Prunus × cistena) is a cross between Prunus pumila and Prunus cerasifera. 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.
