Mammillaria spinosissima ‘Red-Headed Irishman’ is a striking globular cactus known for its dense covering of deep reddish to copper-colored spines that form a dramatic “cap” over its green stem. As it matures, it often produces clustering offsets, creating a tight mound of colorful, spiny globes that stand out in cactus collections and rock gardens. In spring, it may bloom with rings of small pink to magenta flowers near the crown, adding seasonal contrast to its bold spination. This drought-tolerant cactus thrives in full sun, well-draining soil, and requires minimal watering.
Pet Friendly: Generally yes. Mammillaria spinosissima ‘Red-Headed Irishman’ is considered non-toxic to cats and dogs. However, its dense spines can cause injury or irritation, so it should be kept out of reach of pets.
