Viola triloba, growing as a native in Northwest Georgia on a dry rocky slope. Here is another link with some good close up photos of this variety of violet.
I didn't gather all the flowers growing on any one plant and I did not take all the flowers at that location. Some insects may be relying on these wild violets as their food source. Although as I was gathering at approximately 4 pm, at about 66 F, I did not see any bees or other insects on the flowers.
