(Ulmus japonica x wilsoniana’ Morton’) is characterized by arching limbs and a graceful vase shape like that of the classic American Elm. Its glossy dark green foliage changes to yellow in the fall and is resistant to elm leaf beetle feeding as well as Dutch Elm Disease and Phloem Necrosis. This fine cultivar derives from an outstanding specimen tree growing at Morton Arboretum (pictured). Heat and drought resistant, this Chicagoland Grows introduction also shows good nursery form and appears to be one of the best of the hybrid elms. The parent tree, according to information released by Chicagoland Grows, Inc., is a hybrid of U. japonica x U. wilsoniana. Allee Elm

Resistant to Dutch elm disease. Voted 2003 Urban Tree of the Year by the Society of Municipal Arborists. Athena Classic

Beauty meets utility in this heat and drought tolerant elm. Its adaptability and mannerly, vase-shaped growth habit result in an easily grown, premium shade tree. Highly resistant to disease and insect attack, it adapts to varied growing conditions and pH levels, and thrives in tough urban settings. True to its name, Emerald Sunshine® Elm thrives in the hot summer sun while casting cool green shade. Leaves retain their fresh, green appearance through the hot days of summer, when drying winds cause damage to less heat-adapted trees. Strongly textured foliage emerges with red tints and matures to a deep, rich green. Fall color is rich yellow, sometimes with purple tints on the tips and along the margins. Leaves are also highly resistant to the feeding of elm leaf beetles, according to university researchers conducting a 10-year nationwide performance trial. In addition to warding off insect attacks, this versatile performer resists Dutch Elm Disease and Phloem Necrosis. Selected on the arid plains of western Oklahoma by plantsman and elm enthusiast Steve Bieberich, this compact, carefree elm was chosen as the best performing plant grown from Ulmus propinqua seed collected in China. Maturing smaller than most elms, it develops a vase shaped canopy as it reaches about 30 feet in height with a spread of about 25 feet. A strong central leader and upright, symmetrical and mannerly growth habit make it an easy-care tree in the nursery as well as in the landscape and on the street. Hardiness is USDA Zone 5.
