What is patriot elm tree?

The Patriot Elm tree (Ulmus 'Morton') is a disease-resistant cultivar of the American Elm tree. It was developed in the 1990s by Dr. George Ware of the Morton Arboretum in Illinois, USA. The tree has a uniform, upright growth habit with a rounded canopy and dark green leaves that turn yellow in the fall. It can grow up to 50 feet tall and 40 feet wide, making it a great shade tree for parks and residential landscapes. The Patriot Elm tree is resistant to Dutch Elm Disease, a fungal disease that has decimated populations of American Elm trees across North America. It is also tolerant of environmental stresses such as drought, pollution, and compact soils. The tree is easy to grow and low maintenance, requiring only occasional pruning to maintain its shape.
