— North Carolina State Cooperative Extension.Helianthus tuberosus — commonly known as Jerusalem artichoke, sunchoke, sunroot, wild sunflower, or earth apple — is an herbaceous perennial edible root vegetable that is a species of sunflower in the Asteraceae family. It is native to the eastern and central United States and parts of Canada.
Helianthus tuberosus grows 5 to 10 feet tall (1.5–3 m). The leaves have a rough, hairy texture. The flowers are yellow, 2-4 inches in diameter ( 5–10 cm), with 10–20 ray florets and 60 or more small disc florets. The flowers are briefly fragrant, giving off a light, vanilla-chocolate perfume.
The plant's tubers are edible, similar in texture to water chestnuts, with a nutty flavor. They may be boiled, mashed, roasted like potatoes, or eaten raw. They do not contain starch like potatoes; instead contain inulin, which converts to fructose, and may be tolerated better by diabetics. The knobby tubers are harvested in the fall, approximately two weeks after the flowers fade (October-December).
Despite its common name, Jerusalem artichoke is not an artichoke and not associated with the city of Jerusalem. The 'artichoke' in its name comes from its similar taste. 'Jerusalem' is believed to be a corruption of the Italian word 'girasole,' meaning sunflower. Italian settlers in the United States likely referred to the plant as girasole because it resembled sunflowers.
