Fun Facts

The Jerusalem Artichoke is in the genus Helianthus along with the common sunflower, and may be confused with it or other species in that genus. However, none of the other species have tubers.

It is rumored that the name ‘Jerusalem’ came from a mis-pronounciation of its name in Spanish (girasol) and Italian (girasole), which literally mean ‘spinning sun.’
