Winged Elm is a deciduous tree that may grow 40 to 60 feet tall. The leaves are alternate with a doubly toothed margin and unequal base. The bark is red-brown to ashy gray with flat-topped ridges that are separated by irregular fissures. In late winter, small red flowers mature in clusters. The tree produces a 1/4- to 1/2-inch flattened samara with a hairy margin.

Fire Risk: This plant has a low flammability rating.
