Jefferson American Elm is a tall native deciduous tree with upward sweeping branching forming a vase-shaped habit. The toothed dark green leaves are rough with asymmetrical bases and turn a vibrant yellow in fall. Inconspicuous green flowers bloom in spring before the foliage. Grows best with full sun and rich well-drained soils. Tolerates drought and urban pollution. Jefferson is a sterile cultivar and has excellent Dutch Elm disease resistance.
