American Elm (Ulmus americana)

American Elm

Truly one of the most striking of all large shade trees, the American Elm can attain heights of over 120 feet and spread over 150 feet. The typical form is vase shaped and spreading. These elms were used as street, park, and estate trees for many decades. The introduction of Dutch Elm Disease, in the 1930’s has all but eliminated the importance of American Elm from urban plantings. This species will tolerate many soil types and is very drought tolerant. The upright form lends itself for use as a street tree. No wonder it was used so widely. Recently another disease organism Elm Yellows, or phloem necrosis is devastating collections of elms. There is no control for this disease and tree removal to prevent the spread is the only alternative. There is hope, however for using elms as a specimen tree again. There are several varieties such as Homestead, Accolade, Frontier that are disease resistant. These trees are genetic crosses with Asian Elms such as Ulmus parvifolia. Another variety known as Triumph is also resistant to Yellows as well. I would not suggest widespread planting of these by any means, but a few specimens can be used for street and park planting. Some native seedling trees are also showing some disease resistance as well. Maybe in the future American Elm can once again shade our streets, parks, and school yards.
