Canon Ellacomb, very good authority, says the prevalent idea that Jerusalem Artichoke is from the Italian "Girasole" turning with the sun . "Sunflower," is nothing more than a clever guess. He says the Italians do not call the plant Girasole, but Carciofo. There are other plants with the prefix Jerusalem, i. e., Jerusalem Sage, Jerusalem Oak, Jerusalem Thorn, Jerusalem Cowslip, etc, none of which ever came from Jerusalem. And if we would know why this plant is called Jerusalem Artichoke, we must look back through the centuries and find out why the name Jerusalem was given to such things as these. There was probably a meaning, but the meaning has been lost.
