Opposite, pinnately compound, 8 to 12 inches long, with 7 toothed or
smooth-edged, 3 to 5 inch, oval to lance-shaped leaflets, green above and paler

the new leaves in spring.
Fruit
1 to 2 inches long, single-winged, flattened but with a rounded seed cavity, in
crowded 6 to 8 inch clusters.
Bark
Ashy gray to brown, with interlacing corky ridges forming obvious diamonds; may be scaly on older trees.
Twigs

Values and Uses
The wood is tough, elastic, and shock resistant, with a pleasing grain. It is used for tool handles, baseball bats, oars, furniture and interior finish. Birds and wildlife eat the seeds; beavers and rabbits eat the bark. White ash is planted as a shade tree and sometimes to prevent soil erosion.
