A walk in the woods

My mother-in-law lives in a quiet residential area with natural wooded wetlands in her backyard. Oftentimes she tells tales of the deer, raccoons, squirrels, woodpeckers, hummingbirds and various other birds that frequent the feeders in the backyard. The wetlands also bring much of an insect population in the heat of the summer...but during the spring thaw it's quite nice.

I've never noticed this kind of wild-flower in the forest by her home before. On Easter Sunday we had a lovely lunch at a restaurant - new to us this year - and then made our way back to her home for some dessert and a walk down to the neighborhood playground with the kids and back again.

The delicate little blossoms are white, blue, purple or pink, and are sprouting under the trees and around the wooded area. Does anyone know what they are?
