Green Ash
Fraxinus pennsylvanica

Leaves are compound, opposite and deciduous, with 5-9 ovate leaflets. Twigs are green-brown and flattened at the nodes with a dark brown, suede-like terminal bud. The leaf scar is shield-shaped with the lateral bud sitting above the scar. Bark is gray to brown with corky interlacing ridges forming a diamond pattern. Fruit is a winged samara and the wing extends half the distance down the body. Form is up to 36 m (120 ft) in height and 1 m (3 ft) in diameter. Green ash is found on fertile, moist to intermittently wet soils in the east and central U.S. and is intolerant of shade. Green ash is distinguished from white ash by lateral buds above the leaf scar rather than within the leaf scar, and wing extending farther down the seed body. The hard wood is used for handles, baseball bats, furniture and crates.
