Ulmus americana, commonly known as American elm, white elm or Gray elm, is native to eastern North America, ranging from eastern North America, occurring from Nova Scotia west to Alberta and Montana, and south to Florida and central Texas. It is known for its large size, reaching heights of 60 to 80 feet and widths of 40 to 70 feet. It thrives in moist, well-drained clay or loamy soils and prefers full sun to partial shade. Unfortunately, like all native elms, Ulmus america is susceptible to Dutch Elm Disease. For plantings use Ulmus americana cultivars that are Dutch elm disease resistant.
