This native of northern China was introduced in colonial times as a food source for silkworms. Although the silk industry did not succeed, the non-native tree thrived and has since spread throughout almost the entire U. S. It aggressively colonizes open areas, displacing native species, and is considered problematic in many states. Both Alexandria and Arlington list it as invasive.
