Slippery Elm is a native deciduous tree with a vase-shaped to broad rounded crown, downy twigs, and red buds that are noticeable in winter.  The serrated, rough dark green leaves with asymmetrical bases often emerge with a red tint and turn an undistinguished dull yellow in fall.  Inconspicuous red flowers bloom in spring before the foliage and give way to papery wing-like seed pods that mature mid-spring.  Grows best with full sun and rich, moist well-drained soils. Tolerates light shade.

Ulmus rubra is host plant for several butterfly and moth species.
