Summary

Mammillaria bombycina, commonly known as Silken Pincushion Cactus, is an evergreen succulent native to the arid landscapes of Central Mexico, where it thrives in rocky outcrops and slopes. It reaches a modest height of 20 cm (8 in) and can spread indefinitely through the formation of offsets. This cactus is characterized by its bulbous tubercles adorned with downy white hairs, short white spines, and distinctive longer brown curved spines. During spring and summer, it produces circular clusters of deep pink flowers on its upper surface, adding to its ornamental value. The flowers are quite showy, attracting pollinators and adding a splash of color to the cactus’ appearance.

The Silken Pincushion Cactus is celebrated for its ease of maintenance and is a popular choice among cacti enthusiasts. It is often grown under glass with heat in temperate regions and requires full sun exposure to thrive. Its drought tolerance and low water requirements make it an ideal plant for xeriscaping and rock gardens. It has earned the Royal Horticultural Society’s Award of Garden Merit, indicating its exceptional performance in cultivation. Propagation is typically done through seeds collected from ripe fruits. While generally pest-resistant, it can be susceptible to root rot if overwatered or if the soil does not provide adequate drainage.CC BY-SA 4.0
