Elms enjoy huge popularity as ornamentals by virtue of their rapid growth. The Siberian Elm is a small to medium sized tree with an open, round crown of slender, spreading branches. Generally measuring from 50-70 ft. tall with a spread equal to three-fourths its height. Siberian Elm has relatively small leaves (rarely more than 2 inches long) that are symmetrical at the base. It is the hardiest of all elms and does well even in areas with cold winters and long periods of summer droughts and is resistant to Dutch Elm. Flowering occurs in spring; small greenish flowers are produced in drooping clusters of 2 to 5. After flowering, a single seed forms in the center of each fruit.
