Edit: I don't know that it's a palm, though. Someone already has a palm Christmas Tree, and the market just started today.
I don't know it either, but that's my bet. The only Christmas Palm we know of is bred. And it feels somehow similar to the situation with 2012 Easter Bunny (the one with tulip). There were some bred ones, but the parentless ones were obtained via Egg Hunt. The time will tell if I was right, though
