Christmas Tree, Moscow, Russia

Plants
Since the 19th century, the poinsettia, a native plant from Mexico, has been associated with Christmas. Other popular holiday plants include holly, mistletoe, red amaryllis, and Christmas cactus. Along with a Christmas tree, the interior of a home may be decorated with these plants, along with garlands and evergreen foliage. Potted pines used to be popular, however these need direct sunlight, and do very poorly as a houseplant. These often come with very inexpensive small ornaments (as shown at upper right), tied to the delicate branches with soft pipecleaners, and sometimes with a small light set (which was often too hot for the tree).
Wreaths are made from real or artificial conifer branches, or sometimes other broadleaf evergreens like magnolia (especially in the American South) or holly. Several types of evergreen or even deciduous branches may be used in the same wreath, along with pinecones and sprays of berries, and Christmas ornaments including jingle bells. A bow is usually used at the top or bottom, and an electric or unlit candle may be placed in the middle. Christmas lights are often used, and they may be hung from door or windows, and sometimes walls, lampposts, and light fixtures, or even statuary.
