Physical Characteristics
Height, size, and shape of elm trees
Elm trees are typically tall and slender in shape, with some varieties reaching over 180 feet in height. Most elm trees are vase-shaped, while others may be more upright or spreading. Their diameter can range from 1-2 feet depending on the species and age of the tree. While most elm trees are single-trunked, some specimens may split into two or more trunks as they age.
Leaf shape and color
The leaves of elm trees are typically oval or obovate with a double-serrated margin. Depending on the species, they range in size from 2-4 inches long and 1-2 inches wide. The leaves are generally green but can sometimes appear yellowish or reddish, depending on the variety. In autumn, elm trees produce yellow, orange, and red foliage.
