Ulmus americana, generally known as the American elm or, less commonly, as the white elm or water elm, is a species of elm native to eastern North America. The trees can live for several hundred years. It is a very hardy species that can withstand low winter temperatures, but it is affected by Dutch elm disease.
The wood was seldom utilized until the advent of mechanical sawing. It is the state tree of Massachusetts and North Dakota.
