Softly pyramidal in youth, this 50-75 ft., deciduous tree, develops an upright, spreading habit at maturity. Crown shape ranges from irregular and somewhat unsightly to a symetrical, round-topped silhouette. Leaves up to 8 or more inches long, divided into 5 to 9 1eaflets with smooth to slightly toothed margins and pointed tips. Deep-green summer foliage turns yellow in fall. Flowers small, in clusters, male and female on separate trees. Fruits in conspicuous clusters, dry, winged, resembling a paddle with a rounded or pointed blade, wing extending alongside the seed halfway or more to the base.
The most widespread native ash, this species extends westward into the plains and nearly to the Rocky Mountains. A northeastern variation with twigs, leafstalks, and underleaf surfaces all densely covered with hairs has been called Red Ash. One of the most successful hardwoods in the Great Plains shelterbelts, hardy, fast-growing Green Ash is also planted on spoil banks after strip mining, as well as for shade.
