This close relative of communis is widely cultivated in North America but perhaps not truly naturalized. Two Ky. colls. suggest occasional persistence in abandoned gardens: from EDMO (M. Medley #18975-88 for WKY) has been been identified as G. italicus P. Mill.; and a coll. from GRAV (R. Athey #2181; check EKY) as G. segetum Ker-Gawl. The latter has been combined with italicus in recent treatments (FNA 26).
