Can you help me identify this plant? I found it in my community garden plot in the Virginia Coastal Plain. It has small, heart-shaped green leaves (1-2 inches). In 3 years I have never seen it flower. The stems are square, red, and white. The stems are connected to rather large (compared to the leaves) roots which are tubers or rhizomes. The roots go pretty deep in the ground and the stems pull away very easily from the roots. The plants spread in a clumped area. I placed a lot of the roots and some of the leaves together in the photo.
