Crinkle-Root, as this plant is known to country children, possesses a long, edible rootstock, crisp and peppery and well worth the trouble of digging it up. The leaves rising from the rootstock stand up on long petioles, and are compounded of three broad, ovate, toothed leaflets. There are two similar leaves on the flowering stem nearly opposite one another.
This is one of our early bloomers, found in company with the Anemones and Bloodroots, and following the Hepatica. The flower is a white cross, the inflorescence a terminal raceme, the fruit a flat pod. While the plants do not exactly grow in beds, there are many together, so that one might say they grow in communities.
