All wise, happy-go-lucky country youngsters know where and when to root out the edible pear-shaped tubers of this beautiful climbing vine, which is familiarly known to them as the Wild Bean. During the early Colonial days, this tuberous root is said to have been used as a substitute for bread. The slender, twining stem has a milky juice, and grows several feet in length. From five to seven broad, toothless, lance-shaped leaflets, with their acute apex and rounding base, make up the stemmed leaf. The numerous rich, brownish purple, butterfly-shaped flowers are sweetly scented, and are densely clustered in a rounding or lengthened head, terminating a short stem from the angle of the alternating leaves. The Groundnut loves the thickets in low, moist ground from New Brunswick to Florida, and west to Minnesota, Kansas, and Louisiana; and blossoms from July to September.
