Are these the coolest Christmas trees in the world?

“O Christmas tree, O Christmas tree, thy leaves are so unchanging.” Or so the lyrics of the popular Christmas carol go. But Christmas trees around the world are no longer traditional evergreen firs. Instead, they’ve taken on unique and diverse forms, with variation in color, size and shape.

Some aren’t even trees at all.

The Christmas tradition of decorating a tree is believed to have its roots in pagan and Christian winter celebrations, where fir tree branches were used to decorate homes to remind people of spring, or as a symbol of “everlasting life.”

While there were a number of forms of early Christmas trees, the first recorded appearance of a Christmas tree in a town square is said to date back to 15th or 16th century Latvia. Townsfolk are said to have danced around the trees before setting them on fire.
