Yacon, another name for chrysanthemum potato, is called "ten thousand strips" in Sichuan, China. It is a perennial herb of Compositae, native to the Andes in South America. The inhabitants of the Andes grow this plant as a root vegetable. The tuberous root of Jerusalem artichoke is rich in water and fructooligosaccharides. It tastes sweet and crisp and can also be eaten as fruit. In the market of Taiwan Province Province, vendors sell the tuberous roots of chrysanthemum potatoes in the name of "underground fruit" or "Tianshan Saussurea". In fact, chrysanthemum potatoes and Saussurea involucrata are two different plants.
