Virginia winged rockcress, Planodes virginicum

There are an awful lot of little white-flowered plants in the mustard family. Most of them tend to be a bit weedy. Filmy white patches drifting across a fallow field only seemed interesting as a possible image of the drift. A few clear flowers in the foreground, the rest fading off? But wait! Flat pods? This time it was something different. This turns out to be the first record of this American native in Michigan. It was not unexpected. These have been slowly drifting north, mostly with the help of agriculture. Virginia winged rockcress is known from AL, AR, CA, DE, FL, GA, IA, IL, IN, KS, KY, LA, MD, MI, MO, MS, NC, NE, OH, OK, PA, SC, TN, TX, VA, and WV. Lenawee Co MI, 5/3/20. Mustard family, Brassicaceae.
