Xmas Tree

Here's what Wikipedia has to say on the matter of xmas trees!
The Christmas tree is a decorated evergreen coniferous tree, real or artificial, and a tradition associated with the celebration of Christmas. The Christmas tree is traditionally brought into the home and decorated with Christmas lights (originally candles), ornaments, garlands, tinsel, and candy canes during the days around Christmas. An angel or star may be placed at the top of the tree, representing the host of angels or the Star of Bethlehem from the Nativity.
The earliest accounts of decorating an evergreen tree at Christmas were recorded in Livonia (modern-day Estonia and Latvia) in the 15th century.
The Christmas tree is sometimes called a Yule tree, particularly by those who wish to avoid Christian connections, but others explicitly distinguish between the two or identify the Yule tree with an undecorated evergreen tree.
