New Harmony Elm

New Harmony Elm is a large deciduous shade tree valued for its classic American elm form, graceful arching canopy, and strong landscape presence. This selection brings broad summer shade, attractive green foliage, and timeless street-tree character to large lawns, parks, campuses, and spacious residential landscapes.

Why choose New Harmony Elm?

Choose New Harmony Elm for the beloved look of an American elm with a refined, high-arching silhouette and excellent shade value. Its vase-shaped habit creates an elegant canopy over open spaces, while the medium-green foliage gives a full, cooling effect through summer. This tree is especially useful where a stately native-style shade tree is desired for a lawn, streetscape, park, or long-view landscape. New Harmony Elm is also recognized as a cultivar selected for improved Dutch elm disease tolerance compared with many older American elms.

Common Name: New Harmony Elm

New Harmony Elm Additional Information

New Harmony Elm offers the classic American elm silhouette that once defined many traditional streets and town greens. Its canopy becomes broadly vase-shaped with age, creating graceful upward and outward branching that provides generous shade. The foliage is green, serrated, and elm-like through the growing season, typically shifting to soft yellow tones in fall before dropping. Small flowers appear in early spring and are not highly ornamental, followed by flat winged seeds called samaras.

This cultivar is best used in large open landscapes where its mature height, canopy spread, and root system have plenty of room. It works well as a specimen shade tree, street tree, park tree, or lawn tree in sites with good soil volume and overhead clearance. Young trees benefit from structural pruning to encourage a strong central leader, broad branch spacing, and a balanced canopy. Place it thoughtfully away from tight foundations, narrow strips, and overhead wires.

Planting & Care

1. Planting: Plant New Harmony Elm in full sun to partial shade with moist, well-drained soil. Choose a spacious site with room for mature canopy development, roots, and overhead clearance.

2. Watering: Water deeply after planting and keep the root zone evenly moist during establishment. Established trees adapt to average landscape conditions, with supplemental watering helpful during extended dry periods.

3. Mulching: Apply a wide mulch ring over the root zone to conserve moisture, moderate soil temperature, and reduce competition from turf. Keep mulch pulled back from the trunk.

4. Pruning: Prune while young to develop strong structure, well-spaced scaffold branches, and a clean central leader. Remove damaged, crossing, or crowded branches during dormancy as needed.
