Description

It will reach about 6 feet (1.8 m) tall with great age. Nocturnal, white or yellow flowers are rarely produced.

The fairy castle cactus rarely blooms. Cacti need perfect growing conditions to produce flowers and the plants in the Cereus family bloom at night. Fairy castle cactus flowers are large and white and usually will not occur until the plant is ten years old or more.

They should be fertilized during their growing season in the summer with a good oragnic fertilizer.
