I’ve been trying to help my in-laws ID this invasive plant from their garden bed. So far, we have only found what seems to be look a likes. It doesn’t have a strong scent and they don’t flower as the season goes on. My mother in law said they were accidentally brought along with the peonies that she took out of her mother’s garden bed. Years later, my father in law moved some lambs ear to another bed they have and that same invasive plant came along with it. Any ideas?
