A Christmas tree is a decorated tree, usually an evergreen conifer, such as a spruce, pine, or fir, or an artificial tree of similar appearance, associated with the celebration of Christmas. The most common types of real Christmas trees are firs, spruces, and pines, which are coniferous trees that grow and thrive in different locations. Here are some of the most popular species often used as Christmas trees:
