Hello, is anyone able to help me identify what this plant is? I didn't plant it, and a few others like it popped up in various spots over the garden last year. It looks very much like it must be a member of the brassica family, but I can't quite pin down which one. Was wondering if anyone else here had come across them before and could shed some light on the matter! I don't mind them, they're quite pretty and the bees like them, and they give me somewhere to transplant any caterpillars that invade my purposefully planted brassicas, but I am curious to know exactly what they are. Thanks.
