Ulmus crassifolia (Cedar elm)
Marcus, Joseph A.
Cedar elm is a large, oval-rounded tree growing 50-70 ft. high and 40-60 ft. wide. Bark is scaly and the drooping branches have corky ridges. Dark-green leaves are small and rough-textured. Leaves much smaller than those of the American Elm, Fall foliage is yellow except in the southern part of the range where it is evergreen. Tree with rounded crown of drooping branches and the smallest leaves of any native elm.

The common native elm in east Texas where it is planted for shade. Called Cedar Elm because of the rough, cedar scale-like texture of the leaves and because it is often found in the western part of its range with Ashe Juniper (Juniperus ashei), which is locally called cedar. The Latin species name means thick leaf.

Conditions Comments: Cedar elm is a nicely-proportioned, hardy, drought tolerant shade tree for a broad range of soil types. It brings vivid yellow color to the landscape in autumn. No need to rake the small leaves—they compost nicely. Young trees have corky wings on their branches. The Mourning Cloak and Question Mark butterflies use it for larval food. Withstands drought and heavy, infertile soils. Susceptible to Dutch elm disease. Reasonably fast-growing. Known to cause severe allergy reactions.
