Christmas tree horticulture is rather fascinating.I'd probably assume the above picture is plastic but if anyone could pull it off it would be the Japanese. The Japanese have a history in creative horticulture that goes back to the samurai arts of flower arranging and the care of ancient bonsai plants.
Side Note: I don't really mind faux horticulture when it comes to Christmas trees.
