Doesn't matter at the moment whether what you have is considered a weed or a flower (a weed is really only a flower in the wrong place.) Enjoy the mystery, let nature 'do its thing' and see if you like the result. If you do, enjoy the randomness and unexpected beauty; if you don't, you know what to dig/pull out next year! Also, if you watch its full development you will be able to identify it more easily and the decision about keeping it or not will become obvious. All plants have their place in the wildlife chain and something, somewhere will appreciate it as a scource of food or shelter. Go with the flow and let it grow...
