The American Elm species of deciduous tree native to eastern North America. The Ulmus Americana occurs naturally from Nova Scotia west to Alberta and Montana, and south to Florida and central Texas.
The American elm is an extremely hardy tree that can withstand winter temperatures as low as ?42 °C.
This graceful tree was common in parks and along road and fence lines until Dutch elm disease essentially eliminated the American elm in Southern Ontario. Trees in areas unaffected by Dutch elm disease can live for several hundred years.
