Valley Forge elm (Ulmus americana 'Valley Forge') is a cultivar of the American elm that was developed to be resistant to Dutch elm disease. It typically grows to a height of 40 to 50 feet with a spread of 35 to 45 feet at maturity.
The tree has an upright, vase-shaped 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. Valley Forge elm also produces small, inconspicuous flowers in the spring, followed by samaras (winged seeds) in the summer.
Valley Forge 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 hardiness and disease resistance, Valley Forge elm is a popular choice for street plantings, parks, and other public spaces, as well as for home landscapes.
