Pincushion Cactus (Mammillaria spp.)
Pincushion Cactus is a compact, easy-to-love cactus known for its rounded shape and dense clusters of tiny spines that give it the look of—you guessed it—a pincushion. Many varieties stay relatively small and may produce rings of colorful little flowers around the top when mature and happy.
Its manageable size and low-maintenance nature make it perfect for sunny windowsills, cactus collections, and small spaces.
