tall tumblemustard, Sisymbrium loeselii

Sometimes it seems that these pages with introduced species could be called 'Unwanted' posters. Although while we don't really need another weed, this one isn't very common yet. Unless you interpret common to mean vulgar. This mustard kind of stinks. It's not yet frequent enough to have settled on a name. You can take tall, small or false, put one in front of tumblemustard, hedge mustard, or rocket, and you would have a choice from the list of aliases on the unwanted poster. Sisymbrium loeselii has been reported from CA, CO, CT, IA, ID, IL, IN, KS, KY, MA, MD, ME, MI, MN, MO, MT, ND, NE, NH, NM, NV, NY, OH, OR, PA, SC, SD, TX, VT, WA, WI, WV, WY, AB, BC, MB, NB, ON, QC, and SK. Lenawee Co MI, 9/26/20. Mustard family, Brassicaceae.
