Found this growing wild in my pasture. I think it's mint but the leaves aren't close to the stem which throws me off. Sorry the plant is a bit droopy. It started to wilt fairly fast after picking. Stem - square, hollow, fuzzy Leaves - opposite, smaller at the top, larger going down, fuzzy top and bottom, slightly iridescent (like mint leaves due to oils) Aromatic - cats were immediately interested when it was brought inside The close up leaf is about 3" long.
