Mammillaria geminispina
Twin-spined Cactus
Description
Silvery white spines cover whitey cactus (Mammillaria geminispina), a mounding cactus from Mexico, throughout the year. Brilliant hot pink flowers are produced in a ring around the apical meristem (growing point) from late spring through fall, attracting various pollinating insects, while the spines deter predation by herbivores. The small pinkish red fruit are often present at the same time as the flowers, if pollinators are present. It does best in full sun with dry, well draining soil. Established plants are drought tolerant. May take 7-8 years before blooms appear.
