Jerusalem artichoke is a tuber, which comes from the root of a type of sunflower and is not to be confused with the more recognisable globe artichoke, which is a type of thistle. They possibly got their name from 'girasole', meaning sunflower, which is the name Italians migrants into the US gave to them. It's possible that they got their names from Puritans settlers upon arriving in what they called the 'New Jerusalem', upon discovering this native plant.
High in inulin, this tuber is great for diabetics.
