Jerusalem artichoke (Helianthus tuberosus)
From Wikipedia, the free encyclopedia

The Jerusalem artichoke (Helianthus tuberosus), also called the sunroot or sunchoke or topinambur, is a species of sunflower native to eastern North America, from Maine west to North Dakota, and south to northern Florida and Texas.[1] It is also cultivated widely across the temperate world for its tuber, which is used as a root vegetable.[2]

It is a herbaceous perennial plant growing to 1.5–3 m tall. the leaves are opposite on the lower part of the stem, alternate higher up; the larger leaves on the lower stem are broad ovoid-acute and can be up to 30 cm long, the higher leaves smaller and narrower; they have a rough, hairy texture. The flowers are yellow, produced in flowerheads 5–10 cm diameter, with 10–20 ray florets. The tubers are gnarly and uneven, typically 7.5–10 cm long and 3–5 cm thick, and vaguely resembling ginger root, with a crisp texture when raw; they vary in color from pale brown to white, red or purple.[2][3]

Despite its name, the Jerusalem artichoke has no relation to Jerusalem, and it is not a type of artichoke, though they are in the same family. The name Jerusalem is due to folk etymology; when the Jerusalem artichoke was first discovered by Europeans it was called Girasole, the Italian word for sunflower. The Jerusalem artichoke is a type of sunflower, in the same genus as the garden sunflower Helianthus annuus. Over time the name Girasole transformed into Jerusalem, and to avoid confusion some people have recently started to refer to it as sunchoke or sunroot[citation needed], which is closer to the original Native American name for the plant.

The artichoke part of the Jerusalem artichoke's name comes from the taste of its edible tuber. Samuel de Champlain, the French explorer, sent the first samples of the plant to France, noting that its taste was similar to an artichoke.[citation needed]

Jerusalem artichokes were first cultivated by the Native Americans (who called them "sun roots") long before the arrival of the Europeans; this extensive cultivation makes the exact native range of the species obscure.[1] The French explorer Samuel de Champlain found them being grown at Cape Cod in 1605.
