Mammillaria perezdelarosae is a beautiful, small cactus with stems densely covered with spines. It is solitary at first but will offset slowly to form a small cluster in time. The stems grow up to 3 inches (7.5 cm) tall and up to 2 inches (5 cm) in diameter. Areoles on the tips of the conical tubercles bear 30 to 60 white, about 0.1 inches (0.25 cm) long, radial spines and usually one hooked, dark-brown, up to 0.6 inches (1.5 cm) long central spine. Flowers are greenish-white, cream to light pink, and with a slightly darker mid stripe. They are up to 0.8 inches (2 cm) long, up to 1 inch (2.5 cm) in diameter, and appear in late winter.


USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).

How to Grow and Care

To encourage better flowering, allow the plants to enjoy a cooling period in the winter and suspend watering. Unlike many other cacti, which use their ribs as storage devices, the Mammillaria feature raised tubercles, from which spines emerge. When you water, the tubercles will expand to allow for increased water storage. The flowers emerge from the axils of these tubercles on the previous year's growth, which accounts for their interesting halo effect. It's imperative that the cactus is not exposed to prolonged dampness and sitting water. Never let your cactus sit in a dish of water. Lastly, make sure to fertilizer during the growing season for the best results.

Repot as needed, preferably during the warm season. To repot a cactus, make sure the soil is dry before repotting, then gently remove the pot. Knock away the old soil from the roots, making sure to remove any rotted or dead roots in the process… – See more at: How to Grow and Care for Mammillaria.
