Green Ash (Fraxinus pennsylvanica)

Green Ash is a deciduous tree that may grow 50 to 120 feet tall. The leaves are opposite and pinnately compound with 7-9 leaflets. The bark is gray-brown with shallow furrows and crisscrossing ridges which form x-patterns. Small, light green to purple flowers, with no petals, mature in loose panicles in early spring. The tree produces a single-winged, dry, flattened samara with a slender, thin seed cavity that matures in the fall.


Host plant for the Eastern Tiger Swallowtail butterfly and many moths. Bark is eaten by rabbits, porcupines, and beavers. Foliage is browsed by white-tailed deer, and seeds are eaten by birds, squirrels, and other small mammals.
