I found this wild mustard plant growing where I live at a city park in Greene county Ohio. I just want to confirm what species it is. I think its Barbarea vulgaris, but it could also be another mustard species. The plants were only eighteen inches tall (1/2 metre). I also wanted to know if anyone here has any experience using the plant for food.
I've been able to successfully collect seed from wintercress. The seeds are tiny and the chaff is heavier than the seed, so it's not practical to winnow the seed by blowing on it in a shallow dish. I had to pick out the chaff by hand.
