Conservation Status: Introduced - naturalized
An uncommon European weed that seems to have been first introduced in far northwestern Wisconsin (where collected in 1915), later spreading south (Schlising & Iltis, 1961). Like other introduced members of the genus, found in disturbed fields and along roadsides and railroads; rarely in sandy prairies.
