Virginia Waterleaf is a common, early-spring flower under moist, deciduous forests. By midsummer, they die back to the ground. The plant grows across most of eastern United States and southeastern Canada.
This photo may be somewhat misleading, since the leaf in the background does not belong to the waterleaf. I think it is nettle. Also called Shawnee Salad, waterleaf is said to be edible in salads. Teas made from the roots have combatted diarrhea (practicalplants.org). But be careful to correctly identify the plant. I imagine a raw nettle salad is quite painful. You should also be aware that, in some regions, waterleaf is a protected species (Davesgarden.com).
