Mammilium

Mammilium is a genus of small, perennial, evergreen succulent plants native to South Africa. The genus is characterized by its rosette-shaped growth habit, with leaves that are thick, fleshy, and often covered in small, conical bumps or "mammillae," which give the genus its name. These bumps are typically white or cream-colored and are used for water storage. Mammilium plants are often grown for their attractive foliage and are relatively easy to care for, making them popular among succulent enthusiasts. The genus includes several species, with the most commonly cultivated being Mammilium haworthii, also known as the "Christmas Cactus." These plants are typically propagated by leaf cuttings and require well-draining soil, bright, indirect light, and infrequent watering. They are also known to be somewhat drought-tolerant, making them suitable for a variety of indoor environments.
