Discovery Elm

Discovery elm is a named Japanese elm selection with a symmetrical upright, vase-shaped crown and dark green leaves that turn yellow in fall. Its mature height and spread of about 35–40 feet require generous room for the canopy.

Its vase-shaped form suits broad lawns and open planting strips. ## Growing Conditions Plant in full sun. The tree is described as adaptable to soil and is hardy in USDA zones 3–7. The cultivar is reported to resist Dutch elm disease and elm leaf beetles, though resistance does not remove the need to monitor tree health.

Its small flowers are not a major ornamental feature. ## Maintenance Allow enough space for the eventual crown and water during establishment. Check young branches periodically and remove damaged or crossing growth while the tree is dormant.
