USDA Symbol: fram2
Large tree with straight trunk and dense, conical or rounded crown of foliage with whitish lower surfaces. White ash is a 75-120 ft., large-canopied, deciduous tree with dense branching, pinnate leaves, and early fall color. Leaves turn yellow, then change to purple in autumn.
The wood of White Ash is particularly suited for making baseball bats, tennis racquets, hockey sticks, polo mallets, oars, and playground equipment. A variation with hairs covering twigs, leafstalks, and underleaf surfaces has been called Biltmore Ash.

White ash has a medium growth rate. It is not as adaptable as green ash, but is considered superior as an ornamental. Susceptible, like many ashes, to a wide variety of disease and insect pests; these usually are not a problem to vigorously growing trees. Seedlings will tolerate quite a bit of shade, but if a full crown is desired, a generous amount of sun will be necessary as the tree
matures. Prune in fall.
