A Eurasian species locally introduced as a weed of disturbed sites and gardens. Regularly reported from Michigan, but the first collections seen were from Kent Co. in 2011 by W. S. Martinus and E. M. Smith, as a garden weed. This is a distinctive species with entire, non-farinose leaves, non-farinose tepals, a ± square stem, and flowers individually disposed. Our plants appear to be var. polyspermum.
