5.5 foot Green Upside Down Christmas Tree: Unlit . A Green Upside down Tree is exactly what it sounds like: an classic artificial evergreen, flipped. The top of this PVC tree from Artificial Plants and Trees is anchored steadily by a stand. It comes prelit with Dura-lit; lights, so you don't have to figure out how to string lights on an upside down tree. Don't be afraid to turn things upside down this Christmas!
