Origin: Introduced from Eurasia

Herbarium search: CPNWH

Notes: FNA7: "A European native, Erucastrum gallicum was first recorded for North America from Massachusetts and Wisconsin (see J. O. Luken et al. 1993 for history of introduction and spread). It is naturalized in all the provinces of Canada and in parts of the United States, particularly the Midwest. It is an allopolyploid, with the n = 7 component from Diplotaxis erucoides/ D. cossoniana and n = 8 from the E. nasturtiifolium complex (S. I. Warwick and L. D. Black 1993). I have not seen specimens from Maryland."
