The new John Lewis Christmas advert has been released, meaning that it's basically 25 December now.This year's centres around a young boy who wants to grow his own Christmas tree- but not everything is as it seems. The tree turns out to be a mischievous Venus flytrap which causes chaos for the family. Viewers will see how the boy lovingly nurtures the plant from a seed bought at a local market, in the belief he is cultivating a perfect Christmas tree.The fast-growing plant becomes an equally big personality who wants to join in all the fun of Christmas, before the inevitable tear-jerking moment when he is cast out into the cold to make way for a traditional tree.
