Mammillaria spinosissima, known as the "red-headed Irishman," is one of the most beautiful mammillarias. Globular at first, Mammillaria spinosissima grows to 8" in height, forming clumps of columns densely spined with reddish-orange spines. Closely related to Mammillaria pilcayensis. Vivid magenta flowers encircle the columns of bright orange in late winter and spring, providing a startling contrast. Native to Guerrero, Mexico. Requires porous cactus soil with adequate drainage. Bright light with ample airflow. Water thoroughly when soil is dry to the touch. Protect from frost.

APPEARANCE

Part of what makes succulents so fascinating are the myriad ways they express themselves throughout the year, depending on light, season, temperature, soil, and hydration. For those and other reasons, the plants you receive may not look exactly as they appear on our website.
