The Triumph Elm, Ulmus 'Morton Glossy', is a selection that resulted from a controlled cross between Vanguard™ Elm and Accolade® Elm, conducted by Dr. George Ware at the Morton Arboretum. Introduced through Chicagoland Grows, it has an upright habit with strong branching, lustrous dark green foliage and excellent disease and pest resistance. Triumph develops softly arching branches as it matures. An excellent shade tree for home and commercial landscapes, Triumph elm is a wonderful park or street tree, offering excellent disease and pest resistance to Dutch elm disease, elm yellows and elm leaf beetle. Elms are adaptable to a wide variety of soil conditions and come in graceful, vase-shaped and weeping forms. Elms prefer full sun and adapt easily to extremes in pH, moisture, wind and heat.
