The Jerusalem artichoke, (Helianthus tuberosus L.), also known as Sunchoke, can be produced throughout the United States. However, the plant is better adapted to the northern two-thirds of the country than the southern third. Jerusalem artichokes are also often used for pickling purposes. The fresh tuber tastes like a water chestnut and is used in salads. Tubers can also be cooked like potatoes.
