Also known as "Castle Cactus" for its tower-like stems, it is a columnar cactus that tends to cluster over time. Its many upright stems are of a green color, which have well-marked ribs, on which white downy areoles and small grayish-white spines sprout. In the flowering season it blooms with nocturnal creamy white flowers.
