Amur Corktree (Phellodendron amurense)
 |
Amur Corktree (Phellodendron amurense) is a broad-spreading, medium sized deciduous tree that grows 30'-45' tall. It has a short trunk and attractive, horizontal wide-spreading stout branches. This often results in a tree that is significantly wider than it is tall, and flat-topped when mature. Native to northern China, Manchuria and Japan, Amur corktree is hardy to zone 3b. It prefers full sun and is adaptable to many soils. Water needs are moderate to low and it is drought and pollution tolerant with no serious pest problems. Dioecious (having both male and female trees), the corktree has yellowish flowers that appear in May to June. Fruit is in drupes, initially yellow and changing to black. It ripens in the fall and persists into winter. Fruit tends to be messy and it may be advisable to plant male trees only. | |
