‘Valley Forge’ American ElmUlmus americana 60x70' US National Arboretum intro, 1995.
Large fast-growing graceful native once lined virtually every street in New England but declined dramatically due to Dutch elm disease. A good place to go elm-spotting is Castine, Maine. The streets there are lined with these beautiful old giants; it feels like stepping back in time.
At maturity, the trunk can reach 4' in diameter with an immense vase-shaped canopy. Long loose branches blow and sway in a hazy breeze on hot summer days. One of the most wonderful shade trees for northern climates.
Fortunately, several disease-resistant cultivars have been introduced. Valley Forge was selected in Delaware, Ohio, and released after 20 years of testing. Plant more elms!
Soil adaptable, prefers to grow in moist areas along rivers and streams but also grows well in drier places. Salt- and drought-tolerant. Z3/4. (3-6' bare-root trees)
