In his short story, "Christmas Eve," Washington Irving wrote, "The mistletoe is still hung up in farm-houses and kitchens at Christmas, and the young men have the privilege of kissing the girls under it, plucking each time a berry from the bush."
While the custom of removing the berries seems to have been forgotten, the tradition of stealing a kiss under the mistletoe remains widely accepted. But what, exactly, are mistletoes?
Mistletoes are flowering plants (angiosperms) which, although they are capable of growing independently, are almost always parasitic or more specifically, partially or hemi-parasitic. They grow on the branches of host trees and shrubs, sending out roots that tap into their hosts' vascular systems, which they then rely on for uptake of water, mineral nutrients and, to some extent, carbohydrates. It is interesting to note that the word mistletoe translates from its Anglo-Saxon origin as dung on a twig; derived from the ancient belief that the plants grew from bird droppings. (Actually, they grow from seeds found in the bird droppings.)
In the wild, the two varieties of mistletoe most often hung at Christmas both parasitize deciduous trees. The plant originally named
mistletoe, Viscum album, or common mistletoe, is a green shrub,
native to much of Europe and parts of Asia, that produces small, yellow flowers and white, sticky berries, which are considered poisonous. Phoradendron flavescens or P. leucarpum, often referred to as leafy mistletoe, is a North American native, which is very similar in appearance to its European cousin. It ranges across much of the Eastern US, but can also be found in some midwestern and southwestern states. It does not grow as far north as New York.
There is a mistletoe that does grow in our region, however, Arceuthobium pusillum. Known commonly as eastern dwarf mistletoe because of its lack of leaves and reduced visible growth habit, it is a plant parasite of spruce and larch trees.
Considered a potentially serious pest, especially in stands of black spruce, dwarf mistletoe is capable of producing and forcibly ejecting seeds coated with an extremely sticky substance called viscin, which acts like glue, allowing seeds projected onto nearby trees to stick to the limbs, where they germinate, producing radicles (rootlets) that easily penetrate the bark and wood tissue of younger branches.
The growing mistletoe is then able to consume water and nutrients taken up by the host trees while altering hormone production within the infected hosts. Although it may take several years, swelling eventually occurs at the point of infection, leading to the formation of compact masses of brush-like branches, called brooms or witch's brooms. Several mistletoe plants may grow on a single broom, causing decline and ultimately killing the host.
So, now that we know what mistletoes are, how in the world did they come to be associated with smooching on Christmas? Let's start with the Druids.
Believing it to be sacred, the Celtic Druids used mistletoe ritualistically, to ensure fertility and as an offered sign of peace, friendship and goodwill. They also used it in medicine, believing it to be a cure for many illnesses and an antidote to poisons.
Mistletoe was also accepted as protection against dark witchcraft and evil spirits and, as such, gathered and worn around the neck or hung
in a decorative fashion on and in homes. It may very well be that the
modern traditions of hanging mistletoe at Christmas and kissing beneath it stem from these early pagan practices.
Or are these traditions rooted in Norse Mythology; to the story of Baldur the Good, perhaps the most beloved of all the Norse gods; the
son of Odin, god of war and magic and the half-brother of Thor, god
of thunder, lightening, agriculture, and craftsmanship?
Tormented by visions of her son's death, Baldur's mother, Frigga, goddess of love, beauty and destiny, exacted an oath of allegiance from all things; the plants and trees, the birds and beasts, fire, water, iron and all metals; to protect and never harm her son. Somehow she overlooked a small shrub, which grew only on the branches of trees on the eastern slopes of Valhalla; mistletoe.
Upon learning this, the demonic trickster, Loki, contriver of mischief, thievery, fraud, lies, revenge, dark magic, and natural disasters, extracted a poison from the mistletoe and devised a heinous plan. He fashioned a dart out of mistletoe root and soaked it in the poison. He had often watched as the young gods, knowing that Baldur could not be hurt by stones or sticks, or anything hewn from them or forged from metal, would amuse themselves by throwing rocks, limbs, swords, axes and such at Baldur, knowing that none would find their mark. It was considered an honor to participate in such games.
Loki sought out Hodur, the blind and slow, god of winter, darkness
"Surely you would like to be part of this merriment?" Loki
tempted. "Come! Throw this dart at Baldur. I will guide your hand."
Hodur agreed and excitedly released the dart. It pierced Baldur's
flesh and, in just a few moments, Baldur lay dead.
The entire world was overcome with sadness. Every living thing wept.
Frigga prayed relentlessly that her son might be released from death
and, eventually Hel, the goddess of death, did allow Baldur to return
to the land of the living. Frigga was so grateful that she commanded
the mistletoe to produce white berries, as a reminder of her tears.
And she promised a kiss to all who passed under it.
Perhaps this is how mistletoe became a symbol of birth, death, peace, love, and resurrection. Perhaps this is from where the modern traditions of hanging mistletoe at Christmas and kissing beneath it
stem. Whatever the origin, as Christianity spread across Europe, the customs and traditions having to do with mistletoe were assimilated
into the celebration of Christmas.
One last thought if you are decorating with mistletoe this season.
Please bear in mind that the berries are potentially poisonous and that mistletoe used as a Christmas decoration should be kept out of the reach of children and pets.
Merry Christmas! Kiss. Kiss.
