60×70' Released by US National Arboretum, in cooperation with testing by the United States National Park Service, 1995.
Large fast-growing graceful native once lined virtually every street in New England but declined dramatically due to Dutch elm disease (DED). Fortunately, several disease-resistant cultivars have been introduced, including New Harmony, which was chosen for exhibiting exceptional tolerance to DED. It was the second-most tolerant in testing during which thousands of trees were inoculated with aggressive strains of DED.
At maturity, the American elm’s trunk can be 4' (even up to 8'!) in diameter with an immense vase-shaped canopy. Long pendant branches blow and sway in a hazy breeze on hot summer days. One of the most wonderful shade trees for northern climates. If you find yourself in Castine, ME, visit the huge old elms lining every street; you’ll feel like you stepped back in time. Soil adaptable, prefers moist areas along rivers and streams but also grows well in drier places. Plant off the corners of a house and they’ll provide all the shade you need. Salt and drought tolerant. Plant more elms! Zone 4.
