Christmas trees are typically made from evergreen trees, such as fir, pine, or spruce. These trees are chosen for their long-lasting greenery and ability to withstand the cold winter weather. Christmas trees come in a variety of shapes and sizes, from tall and full to small and slender. They are often decorated with colorful lights, ornaments, and other festive trimmings, adding to the holiday atmosphere. The scent of the evergreen needles is also a popular part of the Christmas tree experience.
