Virgina Waterleaf under the Butternut Tree

The butternut tree nearest our house has a very interesting ground cover plant growing in its shade. After much searching I have been able to identify it as Virginia Waterleaf (Hydrophyllum virginianum). Like the Canada anemone it propagates by rhizomes and well as seed and is just as easily transplanted. It looks like another candidate for our natural landscaping plans. This is a picture of the ground-cover with an inset of the flower as seen under the butternut tree. This is a another white flower with a very slight purplish tinge.
