Jefferson Elm

Title

Jefferson Elm

Description

This elm tree, called the Jefferson elm, is one of the original 300 elm trees planted on the National Mall in the 1930s. At the same time these trees were planted, Dutch Elm disease appeared in the United States and infected native American elms. Although many of the original National Mall elms succumbed to the disease, the Jefferson elm is resistant. Scientists with the National Arboretum and Department of Agriculture study this tree and have cloned it to help renew the population of American elms. One of the cloned trees, a propagar, was planted at the White House in 2006.
