Invasive Plant Factsheet
Originally brought to the United States from Asia to combat disease affecting the common pear, this non-native tree, including the popular ‘Bradford’ cultivar, is now planted in high density in a variety of urban and suburban settings. It can spread aggressively outside cultivation. The National Park and U.S. Fish and Wildlife Services consider it a plant invader of Mid-Atlantic natural areas.
