Comments: This is a tall growing perennial which produces bright yellow sunflowers. It is native to the North American Plains. The foliage has a rough, hairy texture. The three to four inch elongated tubers are sometimes used as root vegetables. They vaguely resemble ginger roots. This is not an artichoke. Reported to be an easy perennial to grow, but the quality of the tuber is improved if plants are dug and re-planted each year.
