Zelkova is a medium to large deciduous tree, typically growing to 50-80 feet tall with a spreading, generally upward-branching, vase-shaped crown. It is native to Japan, Taiwan and eastern China. It is noted for its graceful shape, clean foliage, and attractive bark. Zelkova has been promoted in recent years as a substitute for American elm because of its resistance to Dutch elm disease. Insignificant small green flowers appear in spring as the foliage emerges. Fall color is variable, ranging from undistinguished yellow to shades of yellow-orange to red-brown. Smooth gray bark in youth exfoliates with age to reveal orange-brown inner bark. It is valued as a commercial timber tree in Japan.
