  • Posted by jmorth (central Illinois) on Dec 30, 2011 12:25 AM concerning plant:
    Habitat in the wild in Illinois and Indiana is damp rich soil along streams, woodland edge, borders of marshes, ponds, and lakes and moist thickets and prairie. The roots form a necklace like series of fleshy tubers 1 to 3 inches long.
    Important food source for native North Americans and frontier pioneers. The Osage gathered tubers in the fall and stored them for winter use. Pawnee and Meskwaki used them like potatoes. The bean like seeds were used like peas.
    After being informed of the value of groundnuts and how to use them by friendly Indians, pilgrims used them as a major source of food during that first critical winter in 1620. Pilgrim gratitude was short-lived, 34 years later they passed a law forbidding Indians to dig ground nuts on 'English' land.
    The tubers are white and have an 'elastic' texture. Tubers were eaten raw, boiled, or roasted. Tubers can be used in soups, stews,or fried like potatoes (w/ 3 times more protein).
    Broken stems yield a 'milky' sap. Flowers yield a strong fragrance.
    Can be utilized as a container plant.
