Description:
Mammillaria spinosissima, also known as the Spiny Pincushion Cactus or Red Headed Irishman, is a fast-growing cactus native to central Mexico. It thrives in well-drained sandy or loam soils with low humidity and full, filtered sun. This drought-tolerant cactus grows up to 12 inches tall and features purple-colored flowers. It is disease-resistant but can be susceptible to pests like mealybugs. The plant prefers a porous cactus mix soil and requires little watering, making it ideal for xeriscaping.
