Amur corktree is a perennial tree that can grow from 35-45 ft. (10-14 m) tall. The tree has a short trunk with spreading branches. The bark is thick and corky. Leaves are opposite, compound (divided into 5-11 leaflets) and 10-15 in. (25-38 cm) long. Leaflets are elliptical, acute at the apex, 2.5-4.5 in. (6-11 cm) long and smell like turpentine when crushed. Flowering occurs in late spring, when bunches of small, green flowers develop. Fruits are drupes, 0.25 - 0.5 in. (0.6-1.3 cm) in diameter and bright green (black when mature). Amur corktree is native to eastern Asia and was introduced into the United States in 1856. Trees prefer full sun and rich soils. |
