Brassica kaber of Michigan Flora.

A Eurasian native, seldom cultivated but now a widespread weed. Next to Barbarea vulgaris, our commonest “yellow mustard” in Michigan. First noted by D. Cooley, apparently in Macomb Co., about 1841. Now thoroughly established throughout in all kinds of disturbed places and disturbed ground, including roadsides, fields, railroads, dumps, shores, yards and gardens, fencerows; invading forests, both dry and moist.
