Green ash is one of our most adaptable native trees.
The leaves are 10 to 12 inches in length with individual leaflets 2 to 6 inches long. The leaflets are long-pointed at the tip with a tapering base. The leaflets are dark green and glossy on the upper surface, while lighter green below. The margins are usually conspicuously toothed. Branches are stout, round, green and smooth to hairy when young, becoming smooth and turning ash-gray with age with half circular leaf scars.
