Ulmus americana (American elm)
Wasowski, Sally and Andy

Ulmus americana

Ulmus americana L.

American elm, White elm

Ulmaceae (Elm Family)

Synonym(s): Ulmus americana var. floridana, Ulmus floridana

USDA Symbol: Ulam

USDA Native Status: L48 (N), CAN (N)

Three distinct habits are recognized including the vase-shaped form in which the trunk divides into several erect limbs strongly arched above and terminating in numerous slender, pendulous branchlets. A more wide-spreading and less arching form occurs, as well as a narrow form with branchlets clothing the entire trunk. The species usually grows 60-80 ft. Dark-green leaves have variable fall color. Large, handsome, graceful tree, often with enlarged buttresses at base, usually forked into many spreading branches, drooping at ends, forming a very broad, rounded, flat-topped or vaselike crown, often wider than high.

This well-known, once abundant species, familiar on lawns and city streets, has been ravaged by the Dutch Elm disease, caused by a fungus introduced accidentally about 1930 and spread by European and native elm bark beetles. The wood is used for containers, furniture, and paneling. Because of its fundamental architectural form, this is the ideal street tree. Its branches meet across the road in a vaulted arch that permits the passage of high vehicles.(Peattie)
