American elm (Ulmus americana)
Family: Ulmaceae
American elms are large, stately trees that grow naturally across a broad region of North America. They have a distinctive vase-shaped canopy and attractive autumn foliage. Once common in nature and in the landscape, American elms are in decline as a result of Dutch elm disease. Many cultivars are known, and some appear to be partially resistant to the disease. Landscapers continue to plant American elm trees, and they remain a familiar sight in the United States and Canada.
