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.
