In Greek mythology, Persephone unlocked the gates to the underworld with a wand of mistletoe. The ancient druids venerated mistletoe for its powers and held that when the plant was growing on oak trees, as opposed to apple, it was particularly sacred. The tradition of kissing beneath it, based loosely on Celtic lore, became popular in the 19th century along with other yuletide rituals.
