History of the Mistletoe
Mistletoe is a plant that grows on willow and apple trees (and in garden centres). The tradition of hanging it in the house goes back to the times of the ancient Druids. It is supposed to possess mystical powers which bring good luck to the household and wards off evil spirits. It was also used as a sign of love and friendship inythology and that's where the custom of kissing under Mistletoe comes from.
