Kalysta Winged Elm is a native deciduous tree with a strong central leader, a vase-shaped crown, and small cork-like wings on the branches.  The serrated, rough dark green leaves with asymmetrical bases often emerge 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, drought, and urban conditions.  Kalysta is resistant to powdery mildew and other leaf-born diseases.
