About Powder puff cactus
Mammillaria bocasana, commonly known as 'powder-puff pincushion', is a small, globular cactus, often forming clusters, covered in a dense layer of soft, white spines that give it a cottony appearance. It produces small yellow or pink flowers around its apex. It is ideal for cactus collections, rock gardens, or as an indoor plant on a sunny windowsill.
Native range
Central Mexico
Care tips
It requires abundant direct sunlight to thrive and maintain its compact form, though it appreciates slight protection during the hottest summer hours. Water sparingly, only when the substrate is completely dry, especially in winter to prevent rot. Use a very well-draining substrate, specific for cacti. The most common mistake is overwatering, which can be fatal for this species.
