"Lustrous dark green foliage cloaks this easily managed selection. A young, upright-oval form matures to softly, arching branches. Triumph maintains excellent disease and pest resistance as well as good drought tolerance, making it a great choice for tough, urban planting sites.

Special Note
Triumph™ Elm is second in a line of many to be introduced from the elm improvement program at The Morton Arboretum. The program began when the significance of the large, glossy-leaved hybrid elm near the Thornhill Education Center was recognized. Accolade® was the first elm to be commercially introduced from The Morton Arboretum’s tree breeding and selection program. The program was established by Dr. George Ware to test and examine as many species of Asian elms as possible in an effort to find suitable replacements for the beloved but disease-prone American elm."
