Christmas trees are also known by several other names, including Yule trees, Tannenbaum, and holiday trees. The name "Christmas tree" originated from the German custom of decorating a tree with apples, nuts, and candles during the winter solstice festival of Yule. Over time, the tradition evolved into the Christmas tree we know today, adorned with colorful lights, ornaments, and gifts. Some of the other names for Christmas trees include "Fir of Life," "Evergreen," and "Peace Tree."
