I thought so! I knew it is some kind of weed but since we have had chipmunks buried peanuts everywhere in the garden, which made me think of peanut. Usually I would pull any kind of weed or suspicious weeds, but I have no hurry with this one. Will just let it set for some more time until it blooms, then I will post a picture up for you. Thank you every one. You guys' been very helpful!
