Native to North America, Fraxinus pennsylvanica (Green Ash) is a superb, medium-sized, deciduous tree with a straight trunk and a dense crown, pyramidal when young, becoming rounded with age. The foliage of compound pinnate, medium green leaves contains 5-9 leaflets which turn rich shades of golden-yellow in the fall. After dropping to the ground, the attractive silvery-brown bark, ridged and furrowed into diamond-shaped patterns, is revealed, providing winter interest. In mid-late spring, purplish male and female flowers appear on separate trees. The female flowers are followed by drooping clusters of winged samaras, 2 in. long (5 cm), that ripen in fall and may persist on the tree throughout winter. Tough, the wood of Green Ash is particularly suited for making tool handles, oars, garden furniture and sports equipment. Fraxinus pennsylvanica is a splendid shade tree or specimen tree for a large landscape.
