The TRIUMPH™ elm has very good resistance to Dutch elm disease (DED) and to elm yellows; it also has good resistance to elm leaf beetle. It is easily transplanted, quick to establish, and adaptable to most soil types. Large, lustrous, dark green summer foliage gives way to yellow fall color. Useful for home and commercial landscapes or parks or as street tree.
