Wild Potato Vine
Ipomoea pandurata, known as man of the earth, wild potato vine, manroot, wild sweet potato, is a species of herbaceous perennial vine native to North America. It is a twining plant of woodland verges and rough places with heart-shaped leaves and funnel-shaped white flowers with a pinkish throat. The large tuberous roots can be roasted and eaten, or can be used to make a poultice or infusion. When uncooked, the roots have purgative properties.
