John, this is wild violet - a very common plant in lawns and beds in our area.  Some people don't mind them and let them grow.  Their little purple flowers attract tiny pollenating insects, which is good, but they are vigorous and spread quickly.  If you don't dig out all the rhizomes and little bulbs, the plants continue to grow.
Here are a couple Extension sites with more information:
