Cotinus coggygria, commonly known as Common Smoketree, Smokebush, Rhus cotinus, Venetian Sumach, Eurasian Smoketree, or European Smoketree, is a deciduous multistemmed shrub native to a vast geographic range stretching from Southern Europe to Central China. It belongs to the plant family Anacardiaceae. This versatile shrub can be grown as a multistemmed shrub or trained into a single-stemmed shrub or small tree, offering a range of landscape possibilities. With its unique and eye-catching flowers, Cotinus coggygria stands out in the plant kingdom.
In terms of appearance, Cotinus coggygria typically reaches a height of 12 to 15 feet (4 to 5 meters). Its oval leaves are arranged alternately along the stems and feature a bluish-green hue. As autumn approaches, the foliage undergoes a striking transformation, displaying beautiful shades of yellow and red. The flowering period of Cotinus coggygria begins in summer, typically in June. The flowers, which are plumy-haired, grow in panicles that measure approximately 8 inches (20 cm) in length.
One of the most distinctive characteristics of Cotinus coggygria is its long-lasting and color-changing flowers. These flowers, resembling puffs of smoke, gradually transition to a smoky pink color as the seasons progress. Hence, the common name “Smoke Tree” aptly captures this enchanting transformation.
