Ulmus Emerald Sunshine: This heat-tolerant elm is well-suited to urban landscapes

摘要

Elms are terrific landscape trees. They're stately, long lived and relatively fast growing.However, the genus has had its ups and downs. Dutch elm disease was a disaster to the nation's American elm population. As a result, many in commerce shied away from all elms. But Ulmus is making a comeback. New U. americana are being introduced, including 'New Harmony' and 'Valley Forge' with resistance to Dutch elm disease. So American elm is poised to be a great American street tree once again.
