Jerusalem artichoke

Despite its name, the Jerusalem artichoke has no relation to Jerusalem, and it is not a type of artichoke, though both are members of the daisy family. The origin of the name is uncertain. Italian settlers in the USA called the plant girasole, the Italian word for sunflower, because of its resemblance to the garden sunflower (note: both the sunflower and the sunchoke are part of the same genus: Helianthus). Over time, the name girasole may have been changed to Jerusalem. To avoid confusion, some people have recently started to refer to it as sunchoke or sunroot.
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 its taste was similar to an artichoke.
Unlike most tubers, but in common with other members of the Asteraceae (including the artichoke), the tubers store the carbohydrate inulin (not to be confused with insulin) instead of starch. For this reason, Jerusalem artichoke tubers are an important source of fructose for industry. The crop yields are high, typically 16–20 tonnes/ha for tubers, and 18–28 tonnes/ha green weight for foliage. Jerusalem artichoke also has a great deal of unused potential as a producer of ethanol fuel, using inulin-adapted strains of yeast for fermentation.
