The Lacebark Elm, also known as the Chinese Elm, was introduced from China and has very few pest problems. It is resistant to the Elm Leaf Beetle, and is highly resistant to Dutch Elm Disease, and Elm Yellows (Phloem necrosis). However, in eastern Oklahoma, an Elm Flea Beetle can skeletonize the leaves in early spring. The Lacebark Elm has unique decorative lacy bark thus the common name.

Bark: The young bark is a flaky, brown-gray color, but mature bark is flaky with a combination of gray, green, orange, tan, and reddish-brown colors. Its bark, unlike other Elms, is mottled instead of ridged and increases in beauty with age.

Foliage: The 3/4 - 2 1/2 inch long by 1/3 - 1 1/3 inch wide leaves are alternate, simple, and elliptical. Although somewhat leathery at maturity, the leaves turn yellow, gold, orange, red, purple, and green in the fall, and continue coloring until late November.

Flowers: The greenish-yellowish flowers are small and hidden among the leaf axils in the foliage. They bloom from August to early September.

Fruit: The 1/3 inch long, lime green fruit is a samara, and is easily noticed among the dark green, shiny leaves. After ripening from September to October, it turns a deep brown.
