Elm, New Horizon

New Horizon elm (Ulmus 'New Horizon') is a cultivar of the American elm that is known for its resistance to Dutch Elm Disease and its fast growth rate. It typically grows to a height of 40 to 50 feet with a spread of 30 to 40 feet at maturity.

The tree has an upright, vase-like growth habit with a rounded crown, and its branches tend to grow upward and outward. Its dark green foliage turns yellow in the fall, adding to its ornamental appeal. New Horizon elm also produces small, inconspicuous flowers in the spring, followed by samaras (winged seeds) in the summer.

New Horizon elm is tolerant of a wide range of soil types and growing conditions, and prefers full sun to partial shade. It is also resistant to pests and diseases, including Dutch Elm Disease, which has decimated many elm populations in North America.

Due to its resistance to Dutch Elm Disease and its fast growth rate, New Horizon elm is a popular choice for street plantings, parks, and other public spaces, as well as for home landscapes.
