The Catlin Elm is a sport of the common Chinese Elm. It is partly evergreen in mild climates and evergreen in the south. Its leaves are very tiny (0.25" - 0.75" long), are a shiny dark green, and smaller than Zelkova. The Catlin Elm can only be propagated by cutting or layering. It grows slower than the Chinese Elm, but it produces a much finer network of twigs and branches
