Christmas trees are typically coniferous trees, such as pine, spruce, or fir, which are known for their evergreen nature and the ability to keep their needles throughout the winter months. These trees have a festive appearance with their green foliage, which provides a perfect backdrop for decorating with lights and ornaments during the holiday season. Some of the most popular Christmas tree species include Norway Spruce, Douglas Fir, Noble Fir, White Fir, and Eastern White Pine.
