Frontier Elm is a small, fast-growing deciduous tree with an upright pyramidal crown and a fluted exfoliating trunk. The narrow shiny dark green leaves have small teeth turn an attractive reddish-purple in fall. Insignificant fall flowers give way to papery wing-like seed pods that mature mid-fall. Grows best with full sun and rich well-drained soils. Frontier has good resistance to dutch elm disease, elm yellows, and elm leaf beetles. Can tolerate both dry and wet sites.
