Spotted knapweed is an exotic invasive plant that has become widespread in the United States. In the Great Lakes region, spotted knapweed is a common invader on dry sandy soils in disturbed areas like roadsides and abandoned agricultural fields. Spotted knapweed can also invade intact natural areas including dry prairies and dunes. The pages listed below contain information on how to identify and manage spotted knapweed, frequently asked questions (FAQ’s) regarding this plant in Michigan, and information on the potential to use native plants to supply summer nectar and pollen flows.
