These are growing along the east side of the house. At first it looked just like a nice green ground cover, which was fine. But then it started growing stalks with flat clumps of tiny white flowers. It's quite pretty even though it looks like a weed. I'm not sure what it is. I first thought it was Baby's Breath but that looks more clumpy and woody. These look dangly and weedy. But pretty. I'll have to keep an eye on them.
