Any idea what this is called? It's the little plant in the front of the picture. The flowers are really more purple than they look. I imagine it's a wildflower of some sort. I'm sorry the flower stalk is a little fuzzy.

I found this clump of plants out by the side of the road. I dug them them up and brought them to my flower bed because they were about to be dug up for construction. The whole pants are about6-8" to the top of the flower stalk.
