There are a tremendous number of mistletoe traditions and legends – and these pages can only cover a few aspects.
The best-known tradition is the kissing one; – hanging mistletoe high in a room and kissing loved ones, or complete strangers, beneath it, is hugely popular Christmas custom.
It is a remnant of an ancient fertility tradition, helped along by some re-invention in the 18th and 19th centuries when druidic ideas were reborn, and may originally have been rather a local custom and not a genuine national tradition.
It is curious that it is very ‘British’ – traditionally only practised abroad in English-speaking countries (USA, Canada, Australia, New Zealand etc), though becoming popular everywhere in recent decades.
