The original mistletoe, Viscum album, (different from the ornamental North American version) got its name from the Anglo-Saxon word “mistel” for “dung” and “tan” for “twig.” Dung-on-a twig really is an excellent description of the plant’s origin. Mistletoe would often appear on a branch where birds left their droppings which contained mistletoe berry seeds that had passed through their digestive tracts. Interestingly, birds are not bothered by the seeds which are highly toxic to humans.
