A Christmas tree is a type of evergreen tree that is decorated with lights, ornaments, and other festive decorations during the holiday season. It is a traditional symbol of Christmas and is often used as a centerpiece for holiday celebrations. Christmas trees are typically cut down from the wild or grown on Christmas tree farms and can range in size from a few feet to over 20 feet tall. They are often decorated with lights and ornaments, such as stars, candy canes, and other festive items.
