(Phellodendron amurense) The thick, corky branches of the Amur cork tree seem to stretch on for miles, and the deeply furrowed bark gives it an ancient appearance. Believe it or not, the Amur Corktree is actually a member of the citrus family; it produces a curious cluster of small green fruits that in fact smell like citrus when they are scratched. This particular tree is male, so you will not find any fruit on it this fall.
