Callery pear
Callery pear is one of the most rapidly-spreading invasive plants in the eastern U.S. This plant stems from cultivars of ornamental pears, most commonly the Bradford pear. Callery pear can have long thorns, and grows singly or in thick patches in old fields, roadsides, or forested areas.
