Black ash is a small-canopied, medium-sized tree, 40-50 ft. tall. Branches reach upward instead of outward like white ash. Leaves are pinnately compound with leaflets that are finely serrated. Bark is scaly and flaky rather tham ridged and furrowed. Insignificant fall color.

The northernmost native ash, Black Ash takes its name from the dark brown heartwood. Baskets, barrel hoops, and woven chair bottoms are made from thin rough strips of split wood, giving rise to the other names.
