Comments:
Green ash is a medium-sized broadleaf deciduous tree, that develop from a pyramidal to spreading habit at maturity. Leaves are opposite, pinnately compound with 5-9 leaflets. Leaflets are ovate to oblong-lanceolate in shape, with crenate-serrated margins, dark green above and pubescent below. Fall color is yellow-gold. Trees are dioecious with separate male and female trees, and flowers as the leaves unfold. Male flowers are green-purple and clustered. Female flowers greenish, developing into pendent clusters of single-winged samara fruits. Green ash prefers full sun, and trees in our region are threatened by the spread of the invasive emerald ash borer.
