Astrophytum asterias

Astrophytum asterias, commonly known as the Sand Dollar Cactus or Sea Urchin Cactus, is a cactus species native to Mexico. This slow-growing, low-maintenance plant can reach up to 30 cm in height and 15 cm in diameter. Its distinctive round shape with flattened sides resembles a sand dollar or sea urchin, giving it its common names. The Astrophytum asterias typically features four to eight ribs with white woolly areoles along each rib. These areoles produce spines up to 2 cm long, which are usually white or yellowish-brown. In addition, the cactus produces large, yellow flowers that bloom from late spring through early summer. This plant thrives in well-draining soil and requires minimal watering during its growing season, which spans from spring through fall. During its dormant period in winter, it should be kept dry and needs even less water. Astrophytum asterias is an excellent choice for indoor gardening since it performs well under artificial light conditions, making it ideal for those in areas with limited sunlight. Overall, Astrophytum asterias is an attractive and easy-to-care-for cactus, suitable for both novice gardeners and experienced collectors alike.

🌳 The sand dollar cactus is a delicate plant that demands careful attention, yet it remains popular among gardeners in desert and Mediterranean climates because of its unique appearance and beautiful annual blooms. While it is most commonly grown in containers, it can also thrive in a dry succulent garden or a desert-themed rock garden.
