American Elm (Ulmus americana): Classic Shade Tree

American elm, or white elm, was once the premier street tree of eastern North America before Dutch elm disease devastated populations. Disease-resistant cultivars are now reviving its use.

Botanical Profile

Description and Features

This large deciduous tree grows 60–80 feet tall with a distinctive vase-shaped crown. Leaves are ovate, doubly serrate, rough above. Bark is gray, deeply furrowed. Small green flowers appear in early spring before leaves, followed by winged samaras.

Cultivation and Uses

American elm prefers full sun and moist, well-drained soil but adapts to various conditions. It is fast-growing and tolerant of urban stress. Plant only disease-resistant cultivars (e.g., 'Princeton', 'Valley Forge'). Used as a shade tree in large areas.

Historical Significance

Once lined countless Main Streets; its arching branches created cathedral-like canopies.
