Matt says I brought this home and planted this. I must be losing my mind, because I don't remember buying it or planting it. I think it's a weed. The only thing I can think of... is one day I was at a nursery looking at some oregano, but I don't think I even bought that plant that day. And from the pictures I looked up online, it doesn't look like oregano. Anyhow, it doesn't smell, and i'm thinking of just ripping it out. What is it?
