Emerald Sunshine Elm
Arbor Walk #52, Treekeeper ID #1676
This Asian hybrid elm is a relatively small cultivar growing 35 feet high and 25 feet wide. It has glossy green leaves which turn yellow in the fall. This elm cultivar was developed to be resistant to Dutch Elm Disease, which has been a deadly threat to American Elms since the 1930’s, by Steve Bieberich and introduced by J. Frank Schmidt Nursery. Because of this resistance, it serves as an alternative to American Elm in formal uses.
