Common Smoketree
Cotinus coggygria (ko-TYE-nus kog-GIH-gree-uh)
Smoketree, or smokebush, is an upright spreading deciduous shrub or small tree in the Anacardiaceae (cashew or poison ivy) family. It will provide a wide range of garden interest throughout the season. The smoky pink flowers are showy, wispy, and airy and appear in mid-summer. They consist of many filaments which make up a cloud of color on the current season's growth. Fall foliage is reddish-purple and the crushed leaves smell like a radish. While it prefers to be planted in well-drained soil in the full sun it is adaptable to wide range of soil pH. The purple-leaved varieties planted in the shade may have its leaves revert to green. This plant has a fibrous root system which is easy to transplant, and once established, is drought tolerant. Prune it back in late winter 6 to 8 inches above the ground to rejuvenate its shape. This will sacrifice any flowering for that year however. To preserve the flowers leave 1/3 of the old stems on the plant. In the garden, this plant is best used as a large accent plant, single specimen, in masses, or planted in a row as an informal hedge. Smokebush has many cultivars, but the flowers are often sacrificed for the interesting foliage color or bright orange or yellow fall leaf color.
