Triumph™ Elm

Ulmus ‘Morton Glossy’



The Triumph™ elm with its strong, upright branching is easier to train and with its deep green, highly glossy foliage is more attractive as a young tree compared to other elms. The foliage turns yellow in the fall. At a young age, this selection exhibits an upright-oval form becoming more vase-shaped with age. Triumph™ elm has excellent disease resistance, and moderate insect resistance to elm leaf beetle and Japanese beetle. Triumph™ elm was developed through a controlled cross conducted by Dr. George Ware at The Morton Arboretum using Accolade® elm (U. davidiana var. japonica) as the female parent and Vanguard™ elm (U. pumila × davidiana var. japonica) as the male parent. Mature size: 50 – 60’ H, 40 – 50’ W.
