Ulmus americana 'Jefferson'

Jefferson American Elm

'Jefferson' was originally selected by the National Park Service (NPS) from approximately 600 elms planted in the National Mall in Washington, DC in the 1930's for disease tolerance and exceptional horticultural characteristics. It has demonstrated a high level of tolerance to Dutch elm disease. It has the classic American elm vase shape and an expansive crown, dark green leaves that develop early in spring and last late into autumn.

American elms are host plants for several butterflies and seeds are eaten by songbirds and small mammals. The tree provides nesting sites for songbirds and cover for wildlife.
