Can you tell me if this is a plant or a weed?
Hi there, I have the below plant in a pot sharing with a clematis. I don't have a clue what it is. Please advise?
It is a brassica family plant, possibly wild mustard. It is not something you want growing with your clematis and it will self-sow all over. I suggest you cut it at soil level and not pull it out. Pulling will disturb the clematis roots.
