Add a little flair to your book collection with a living plant. The Book Vase by YOY Design Studio is a pot that can discreetly blend in on your shelf. The convincing fake tome features a classy cover titled The Life of Plants outside and the dirt that houses the plant inside. It's waterproof and made from PMMA and PVC, so you don't have to worry about it ruining the other books in your library. And your impressed guests will think that your book spontaneously generated life.
