Allee Lacebark Elm is a tall vase-shaped deciduous tree with pendulous branches and a fluted exfoliating trunk.  The narrow shiny dark green leaves have small teeth that can turn an undistinguished yellow in fall, or occasionally more interesting shades of yellow or reddish-purple.  Insignificant small reddish-green flowers bloom in fall and give way to papery wing-like seed pods that mature mid-fall.  Grows best with full sun and rich well-drained soils.  Allee has excellent resistance to Dutch Elm disease, elm leaf beetle, and leaf scorch.  Can tolerate both dry and wet sites.
