Vick, Albert F. W.

Fraxinus americana L.

White ash

Oleaceae (Olive Family)

USDA Symbol: fram2

USDA Native Status: Native to U.S.

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.

Conditions Comments: 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.

Mr. Smarty Plants says

Question: Our 15 year old Texas ash has less leaf production this year. It also has a small amount of algae on the trunk, and some of the branches have small white spots on it. Also, a few of the branches closest to the trunk have died. Any suggestion would be appreciated.

Question: We have a generous stand of white trillium that has been under the shade of a white oak for many years. Now the 100+ year old oak has died and the trilliums are in the sun. Are we in danger of losing them? If so, how do we save them? We have heard transplanting is very difficult and thought if we planted huge hostas like the sum and substance around the trillium that the hosta would provide shade. What do you think and do you have a better suggestion?
