This plant is familiar to many as a weed. Native to N. America, it can be grown successfully through the U.S. and was widely used from the 16th century as human food and livestock feed.
It's suggested that the name comes from the fact that it was a staple food among N.A. pilgrim, who through they were in "the new Jerusalem".

Jerusalem artichokes are propagated from tubers. Select small, healthy tubers about 2 oz (57 g) with 2 to 3 buds on them. Plant early in spring but wait until soil temperatures are above 40 F (5 C.). Soil should be sandy and well-drained, but fertile. Tubers should be planted 3 to 5 inches (8 to 13 cm) deep, 15 to 24 inches (38 to 60 cm ) apart, in rows 36 to 42 inches (90 to 100 cm) apart. Tubers will begin growing by August but should not be harvested until tops are killed by frost. Care should be taken as it is impossible to find all the small tubers at harvest so if no more plants are desired pull the new shoots in spring as they emerge before they can set more tubers.
