JERUSALEM
Many plants are found to have been named in olden times after the Holy City. The Lungwort, Pulmonaria officinalis, is the Jerusalem Cowslip; Phlomis is Jerusalem Sage; and Teucrium Botrys is the Oak of Jerusalem, called so from the resemblance of its leaf to that of the Oak. In these three cases the prefix “Jerusalem” seems to have been applied for no particular reason—probably because the plants had an Eastern origin. Salsafy, Tragopogon porrifolius, is the Star of Jerusalem, so named from the star-like expansion of its involucre; and Helianthus tuberosus is the Jerusalem Artichoke, a plant of the same genus as the Sunflower, called Artichoke from the flavour of its tubers. The soup made from it is termed Palestine Soup. In the last two cases, Dr. Prior thinks the prefix “Jerusalem” is simply a corruption of the Italian word girasole, turn-sun, and has been applied to these plants from a popular belief that they turn with the Sun. The Lychnis Chalcedonica is the Jerusalem Cross, which has derived its name from the fact that a variety of it has four instead of five petals, of the colour and form of a Jerusalem Cross.
