Have your tree Yule Ball ready or show your love for the Boy Who Lived with Nemesis Nows range of Harry Potter hanging decorations. Here we have a Mandrake, immortalised in resin and ready to hang in your home. A Mandrake, also known as Mandragora, was a magical and sentient plant which had a root that looked like a human (like a baby when the plant is young, but maturing as the plant grows). When matured, its cry could be fatal to any person who heard it.
