I tried planting a baby carrot. Could this be it, or is it something that hijacked my pot? Are those seeds on the ends of the stems?
Oh. Thank you for the ID. The look like they have pretty flowers in the picture, but I don't think I would keep it. I have some other weeds too, and have pretty little yellow flowers. They aren't so bad, but I think I am going to get rid of all of them and keep my pots indoors from now on.
