Range and Habitat in IllinoisCommon Comfrey has naturalized in NE Illinois and scattered counties elsewhere within the state (see Distribution Map). Such naturalized plants are uncommon. Common Comfrey was introduced into North America from Eurasia as a medicinal herb. It is still cultivated in gardens. Habitats include damp grassy meadows, riverbanks, vacant lots, areas along roadsides and railroads, ditches, and waste areas. Areas with a history of disturbance are preferred.
