It’s some sort of mustard. Could you provide a picture where the leaves are not in shadow? Perhaps Sinapis alba if that is a possibilty where you are located .... which is where?

Directly behind it there is some Black Henbane, Hyoscyamus niger. Unlike the edible mustard, the Henbane is highly toxic if consumed. What with the Ricinus at the back you have a good little poison garden going there.

Thanks for the response flora and my garden has some poisonous, medicinal,and spiritual plants. i enjoy the nightshades, especially daturas and brugmansia. I’ve posted a better picture, I hope.,

OK, still thinking Sinapis alba.
