Fairy Castle Cactus is a popular monstrose cultivar of the columnar Cereus. It forms a dense cluster of many short, branching, 5-ribbed stems that grow in a chaotic, turreted pattern, resembling the spires of a fairy tale castle. The stems are spineless or have very short spines. It rarely flowers. A curiosity plant, often sold as a novelty, but long-lived and easy to grow. The 'Floridanus' form is similar.
