One-Spined Pincushion Cactus
Mammillaria spinosissima cv. Un Pico is a unique cultivar of the popular Spiny Pincushion Cactus belonging to the Cactaceae family and native to Mexico. The name "Un Pico" translates to "one spine," referring to its unusual growth habit where each areole bears a single prominent central spine instead of the numerous central spines typically seen in the species.
This distinctive cactus develops attractive cylindrical stems densely covered with fine radial spines, creating a neat geometric appearance. With age, it produces offsets and forms impressive clusters. During the blooming season, rings of bright pink flowers appear around the upper portion of the stem, adding vibrant colour and contrast.
