Popular and beautiful, Mammillaria bombycina (Silken Pincushion) is a small cactus, with solitary or clustered stems, that tends to form a large and gorgeous clump over time. The cylindrical stems, up to 6-8 in. tall (15-20 cm) and 2 in. wide (5 cm), are covered with dense white hairs between the tubercles which are adorned white radial spines and hooked reddish-brown central spines. In spring, it bears deep rose-pink funnel-shaped flowers, 0.6 in across (1.5 cm). Silken Pincushion will produce several complete rings of flowers every year. The blossoms are followed by small pinkish green fruits. Easy to grow and fast-growing, this miniature cactus is perfect for containers. It can be grown as a houseplant, but also grows well outdoors in frost-free climates. Protect from cold, as this species is frost sensitive and only hardy to 23°F (-5°C) for brief periods.
