Mistletoe is a plant traditionally associated with the holiday season, particularly during Christmas. It is often hung in doorways, and the custom dictates that people standing beneath it should kiss. This practice is believed to promote goodwill and strengthen relationships. The origins of the mistletoe tradition can be traced back to ancient Druid rituals and Norse mythology, where it was considered a symbol of peace and fertility. Over time, it evolved into a festive decoration, symbolizing love and friendship during the winter holidays.
