|Triumph Elm – Ulmus 'Morton Glossy' |
Family Ulmaceae – Zelkova, Hackberry, Elm
An excellent shade tree for home, commercial, park or street tree.Hardy to USDA zones 4-9.
Triumphâ„¢ Elm: "Strong, upright branching and a medium texture make Triumph easy to train and much more attractive as a young tree, compared to other elms. As the tree matures, softly arching branches are perfect for parkway and municipal plantings. Triumph also boasts excellent disease and pest resistance along with good drought tolerance." 
This selection resulted from a controlled cross conducted by Dr. George Ware at The Morton Arboretum between Vanguardâ„¢ Elm (Ulmus pumila x Ulmus japonica) and AccoladeÂ® Elm (Ulmus japonica x Ulmus wilsoniana).
Fast-growing Triumph Elm, Morton Arboretum acc. 135-94*1 is 17 years old.
"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.
Size: 20-year size: 30â€™ tall by 15â€™ wide. Mature size: 50â€™ to 60â€™ tall by 40â€™ to 50â€™ wide
Growth rate is fast as a young specimen, up to 3 feet per year, then 1 to 1.5 feet per year until maturity. Attractive as a young tree. Lustrous, dark green foliage in summer. Yellow fall color.

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. AccoladeÂ® was the first elm to be commercially introduced from The Morton Arboretumâ€™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."

Family Ulmaceae – Zelkovas, Hackberries and Elms
There are about 200 species of trees and shrubs in Ulmaceae. Elms fell victim to Dutch Elm disease during the 1950s; until that time, they were the premier shade tree along the streets of our American towns and cities. The Morton Arboretum in past years has bred and marketed five new elm varieties resistant to Dutch elm disease.
