Christmas - The Christmas tree is often explained as a Christianization of the ancient pagan idea that the evergreen tree represents a celebration of the renewal of life. The phrase 'Christmas tree' is first recorded in 1835 and represents the importation of a tradition from Germany, where such trees became popular in the late 18th century.Christmas trees may be decorated with lights and ornaments. Since the 19th century, the poinsettia 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 garlands and evergreen foliage, particularly holly and mistletoe. In Australia, North and South America, and to a lesser extent Europe, it is traditional to decorate the outside of houses with lights and sometimes with illuminated sleighs, snowmen, and other Christmas figures. Municipalities often sponsor decorations as well. Christmas banners may be hung from street lights and Christmas trees placed in the town square. Although Christmas decorations, such as a tree, are considered secular in many parts of the world, the Kingdom of Saudi Arabia bans such displays as symbols of Christianity. In the Western world, rolls of brightly-colored paper with secular or religious Christmas motifs are manufactured for the purpose of wrapping gifts.
