Jerusalem sunchoke Nutrition facts

Jerusalem sunchoke

Jerusalem artichoke is a bumpy, fleshy, root vegetable of sunflower family plants. It's underground nutty, flavorful, the starch-rich root is eaten much the same way as potato in many parts of Western Europe and Mediterranean regions.
It should not be confused to globe artichoke, which is an edible flower bud. Similarly, their name is widely misunderstood as “artichokes from Jerusalem” misinterpreted for the Italian girasole carciofi, translating to sunflower artichoke in English. Some of the common names are sunroot, sunchoke, topinambur etc. Scientific name: Helianthus tuberosus.
Jerusalem artichokes are native to Central America. The plant is technically an evergreen perennial but cultivated as an annual crop. Once established, it grows vigorously reaching about 5-10 feet in height slightly taller than the sunflower plant with multiple branches. Many golden-yellow flower heads appear at the terminal end of branches.
