There are zillions of Indian potatoes growing in back of my house! The city put in a sewer line and the Indian potatoes came up along the edge of the graded right of way. Many of the plants that come up naturally in the Southeast when land is disturbed are actually former domesticated plants cultivated by the Indians. The wild ancestor of the Jerusalem artichoke is a sunflower about two feet tall - which also grows here, but has tiny potatoes. The "selectively improved" Creek version grows up to seven feet tall and produced 1-2 pounds of potatoes. Richard T. **************Looking for a car that's sporty, fun and fits in your budget?
