Range and Habitat in Illinois
In areas where it occurs, Common Groundsel is often locally common, otherwise it is uncommon or absent. In Illinois, Common Groundsel occurs primarily in NE Illinois and a few counties in central Illinois (see Distribution Map). Because this plant is rather inconspicuous, it is possible that official records underestimate its actual distribution within the state. Habitats include lawns, gardens, edges of yards, nursery plots, areas along railroads, and miscellaneous waste areas. It prefers highly disturbed areas where the vegetation is low or scant. Common Groundsel is native to Eurasia.
