Looking at all the Xmas trees for sale it made me wonder, how did this tradition come about. I did a quick check on wikipedia and came away more confused, as they offered a number of possible theories such as evergreen trees being symbolic to German pagans and much later the decorated tree being adopted by European royalty.
What folk lore is there in your countries that tell of the Xmas tree? Or maybe you don't have a Xmas tree but something else. What are your traditions?
