Phellodendron amurense 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.
Foliage
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.
Flowers
Flowering occurs in late spring, when bunches of small, green flowers develop.
Fruit
Fruits are drupes, 0.25-0.5 in. (0.6-1.3 cm) in diameter and bright green (black when mature).
Ecological Threat
This tree is demonstrating invasive characteristics in suburban and urban fringe forests. It escapes intended plantings to invade and displace native hardwood forest. Note: only female plants have potential to become invasive. Phellodendron amurense is native to eastern Asia and was introduced into the United States in 1856. Trees prefer full sun and rich soils.
