Where are sunchokes (Jerusalem Artichokes) native to?

The sunchoke (Jerusalem artichoke) is a species of sunflower native to central North America. It is cultivated widely across the temperate zone for its tuber, which is used as a root vegetable. The tuber contains about 2% protein, no oil, and little starch. It is rich in the carbohydrate inulin (8 to 13%).

Before the arrival of Europeans, Native Americans cultivated it as a food source. The tubers persisted for years after being planted, so that the species expanded its range from central North America to the eastern and western regions.

The tubers are used for cooking and baking in the same ways as potatoes, but unlike the potato they can also be eaten raw. They have a similar consistency, and in their raw form have a similar texture, but a sweeter, nuttier flavor. When raw and sliced thinly, they are fit for a salad.
