What is this plant?
The plant with the heart-shaped leaves could be wild ginger...break off a leaf and smell it, the scent is unmistakable.
The deeply divided leaf appears to be anemone. There are several species, and numerous hybrids, of this plant. Without seeing some blooms, I personally can't narrow it down with any degree of certainty. The foliage looks extremely similar to that of the meadow anemone, as seen on this picture from the Illinois Wildflowers: http://www.illinoiswildflowers.info/prairie/plantx/mdw_anemone.html .
