The Ulmus davidiana, commonly known as David Elm or Japanese Elm, is a small deciduous tree that grows up to 15 meters high. Its dense canopy and slender trunk provide a heavy shade, and its leaves are obovate to obovate-elliptic, with a rough upper surface. The tree produces apetalous flowers in March, with obviate samaras that are less than 19mm long and less than 14mm wide. The David Elm is resistant to Dutch elm disease, elm yellows, and elm leaf beetles. This elm is found mainly in China, Mongolia, Korea, Siberia, and Japan. It is suited to very sheltered, humid conditions and is intolerant of ponding. This tree has shown potential as a landscape tree.
