Pretty in pink...

So when I bought my townhouse, one of the "features" was a raised bed in the front, filled with white stone and a bunch of plants that look like the kind of weeds you find growing in vacant lots. One of those weeds, though, turns into pretty pink flowers for a couple weeks during the summer before they all die and go back to looking like weeds. So I figured I'd get a picture before it gets all weedy again...
