Hi, This thing has been growing in a pot for quite awhile now. I don't recall ever planting it in the pot. Anyway, it looks like a mint plant. Stems are square, and it has a certain smell... well, like mint. But I just want to be sure. Pictures are attached. Thank you very much.
That looks like peppermint. Watch out for 'branches' finding their way into your other pots/nearby dirt - it spreads pretty fast.
