Ulmus americana

With the release of improved, disease resistant American elms, they are once again in demand. ‘Valley Forge’, ‘New Harmony’, and ‘Princeton’ are a few of the cultivars available today. ‘Valley Forge’ is upright, arching, broadly vase-shaped with a full, dense canopy. ‘New Harmony’ develops into a broad vase-shaped crown with arching branches terminating in numerous slender, often drooping branchlets. ‘Princeton’ is also vase-shaped. American elms are adapted to a wide variety of soil conditions, tolerate deicing salts, air pollution, drought, and a range of soil pH. They have yellow fall color.
Exposure: Full sun to part shade
Soil: Prefers well-drained soil
Hardiness: USDA Zone 5-9
