What is a Christmas gnome? They are becoming more popular in the United States, as we see them in many retail stores. From what I have researched, the gnome is a symbol of protector or guardian of precious treasures. The gnome symbolizes good luck and prosperity. They especially love to protect the children of the home. So as you are out shopping to add a few new ornaments to adorn your Christmas tree, think about adding a cute little gnome ornament. There are some larger gnomes that might sit on a mantle. While the gnome may not symbolize the traditional Christmas, I can see the addition as a great conversation topic for your holiday season. They represent goodness, love, and care for those we hold dear, and to me that makes them special!
