American Elm was the dominant street and shade tree throughout much of the U.S., prior to the introduction of Dutch Elm Ddisease. Dutch elm disease was first found in the United States in Ohio in 1930. It has now spread throughout North America and has destroyed over half the elm trees in the northern United Sates. The disease has been reported in all states except the desert Southwest. Research is ongoing to find a way to deal with this problem.

American Elm has a naturally elegant growth pattern and grows to 100 feet, with diameter of 4 feet. The largest tree still alive is in Tennessee and is 122 feet tall, with a girth of 23 feet, 1 inch.
