Jerusalem artichoke is native to North America and may have originated in the Ohio and Mississippi River valleys. The first written account of the plant was a report issued in 1605 by Champlain, a European explorer, who observed Native Americans growing Jerusalem artichoke along with corn and beans in a Cape Cod garden. The species was introduced to Europe in 1612 where it gained popularity as both human and animal food.
