Conophytum calculus, commonly called 'Cone Plant' or 'Living Pebble,' is a small, slow-growing succulent with cone-shaped bodies that remain mostly underground. This South African native produces delicate yellow or white flowers in autumn and is prized for its compact, decorative appearance in rock gardens and collections. It requires minimal water and thrives in well-draining conditions, making it ideal for experienced succulent growers.
