Summary
Baseball plant is a slow-growing, semi-desert succulent native to the Karoo region of South Africa. It forms a globose, ball-shaped stem with eight ribs and grooved seams, often gray-green with pinkish-purple markings; leaves are rudimentary and shed quickly; in summer cyathia appear on the tops of the ridges bearing tiny greenish-yellow flowers, and a milky latex sap is produced when damaged; fruits are three-seeded capsules that explosively release seeds; it is dioecious, with separate male and female plants.
Cultivation favors a sunny position and very well-drained mineral soil; drought-tolerant and watered sparingly, allowing the substrate to dry between waterings; frost tolerance is limited, requiring protection in cold. Propagation is by seed or cuttings, and flowering occurs after several years. Widely cultivated as an ornamental focal point in containers or xeriscapes, it is endangered in its native habitat and protected by conservation laws; the milky sap is poisonous, so caution is advised, and issues such as mealybugs or scale can occur, with rot from overwatering a common risk.
