The Origins of the Mistletoe Tradition

Let’s begin by traveling back in time. Mistletoe is far older than Christmas itself. Its roots stretch into ancient Europe, where it was considered a magical plant by several cultures.


  • Ancient Druids and Mistletoe: The Druids, who were Celtic priests in Britain and Gaul around 2,000 years ago, believed mistletoe had healing powers. They saw it as a symbol of peace and protection, often cutting it carefully with a golden sickle during ceremonies. This sacred plant was thought to bring good luck and ward off evil spirits.


  • Norse Mythology: Mistletoe appears in Norse myths too. According to one famous story, the god Balder was killed by an arrow made of mistletoe. After his death, the plant was considered both dangerous and powerful — but also a symbol of love and resurrection because Balder was later revived.


  • Roman and Greek Influences: The Romans used mistletoe during their Saturnalia festival, a mid-December celebration that influenced modern Christmas traditions. The Greeks also associated mistletoe with fertility and vitality.


Over time, these old beliefs blended with Christian customs and local folk traditions. By the Middle Ages, mistletoe had become a Christmas decoration in Europe, bringing with it a mix of ancient magic and new holiday cheer.

The Meaning and Symbolism of Mistletoe

Why mistletoe? What’s so special about this little green plant with white berries? Its symbolism is rich and varied, and that’s part of why it’s endured through centuries.


  • Love and Fertility: One of the most popular meanings is love and fertility. Many ancient cultures believed mistletoe could promote romance, protect couples, and even increase fertility. That’s why mistletoe became linked to kissing — a symbol of affection and attraction.


  • Peace and Truce: The Druids’ idea of mistletoe as a peacekeeper also influenced later customs. In some traditions, enemies who met under mistletoe would call a temporary truce. Imagine that—a little plant that could stop fights during the stressful holiday season!


  • Evergreen and Eternal Life: Because mistletoe stays green during the coldest months, it’s seen as a symbol of eternal life and renewal. This fits perfectly with Christmas themes of hope and new beginnings.


  • Healing and Protection: Beyond romance and peace, mistletoe was used as a healing herb. Some believed it could cure everything from epilepsy to infertility. While modern science doesn’t support all these claims, it’s a reminder of how mistletoe captured the imagination of many cultures.

The Classic Mistletoe Kissing Tradition Explained

Now, let’s get to the part most of us know best — kissing under the mistletoe. It’s a tradition packed with rules, superstitions, and fun.


  • Where Did the Kissing Tradition Come From? The custom of kissing under the mistletoe dates back to 18th-century England. At holiday gatherings, people would hang mistletoe in doorways or ceilings. Anyone standing underneath was fair game for a kiss — it was a festive way to spread goodwill and maybe spark a romance.


  • The Rules of the Kiss: Believe it or not, there were “rules.” For example, each kiss meant one berry had to be picked from the mistletoe. When the berries ran out, so did the kisses! Also, it was considered bad luck to refuse a kiss when standing under the mistletoe.


  • Why Kissing? The connection between mistletoe and kissing might come from the plant’s associations with fertility and vitality. Plus, kissing was a way to express affection during a time when public displays of love were less common.


  • Modern Day: Today, the kissing tradition is often lighthearted and fun—especially at holiday parties. Some people even use mistletoe as a cute decoration or photo prop. 

Fun Fact:

In Victorian England, mistletoe was so popular at Christmas parties that there was a “kiss count” tradition — every time someone kissed under the mistletoe, they had to pick a berry from the sprig. When all the berries were gone, the kissing stopped! So, the length of your mistletoe kiss session literally depended on how many berries you had.

Surprising Secrets and Lesser-Known Facts About Mistletoe

Mistletoe isn’t just a holiday decoration; it’s got some secrets that might surprise you.


  • Mistletoe is Actually a Parasite: Unlike most plants you find in your home or garden, mistletoe is a parasitic plant. It grows on trees by attaching itself and drawing nutrients from its host. That’s why you often see it hanging high in trees.


  • It’s Poisonous: While mistletoe looks pretty, its berries and leaves contain toxins. Eating mistletoe can be harmful, especially to children and pets. So, if you use real mistletoe in your home, keep it out of reach.


  • Scientific Research: Interestingly, mistletoe extracts have been studied for potential health benefits, including use in complementary cancer treatments in some European countries. This shows the plant’s complex role beyond just folklore.


  • Different Types of Mistletoe: There are many species of mistletoe worldwide, with varying appearances and properties. The one we commonly use at Christmas is mostly Viscum album, native to Europe.


  • Myths Around Mistletoe: Some myths say that mistletoe can ward off evil spirits, bring good luck, or even detect witches. These stories add to the mystique and festive fun of the plant.
