Origin of Name

The genus name "Mammillaria" is derived from the Latin word 'mammilla', meaning nipple, referring to the nipple-like tubercles from which the plant's spines emerge. The species name "spinosissima" translates to "very spiny," highlighting the plant's densely spined appearance. The cultivar name 'Un Pico' means "one peak" in Spanish, indicating this plant's characteristic of typically having a single, prominent central spine per areole, distinguishing it from the often multi-spined areoles of the species standard form.

Technical Description of Plant

Mammillaria spinosissima cv. 'Un Pico' features cylindrical, elongated stems that can grow both singularly and in clusters. The stems are densely covered in tubercles, from each of which emerges a singular, striking central spine, often longer and more pronounced than those found in the typical Mammillaria spinosissima. These central spines can vary in color from reddish to yellowish hues, adding a colorful accent against the green backdrop of the stem. Surrounding the central spine, radial spines form a halo, contributing to the plant's "spiny" appearance. 'Un Pico' blooms with ring-like crowns of small, pink flowers at the top of the stem, adding to its decorative appeal.

Origin of Plant

Mammillaria spinosissima, including the 'Un Pico' cultivar, is native to Mexico, thriving in arid and semi-arid environments. These plants have adapted to their harsh habitats with features like water-storing stems and protective spination to deter herbivores.

Conservation Status

While Mammillaria spinosissima cv. 'Un Pico' is cultivated and does not have a specific conservation status, the wild populations of Mammillaria spinosissima face threats from habitat loss and illegal collection. Efforts to propagate and cultivate plants like 'Un Pico' in gardens and collections help reduce pressure on wild populations.

Care Instructions

Mammillaria spinosissima cv. 'Un Pico' requires well-draining soil and full to partial sunlight exposure. It prefers a dry, warm climate, typical of its native Mexican habitat. Water the plant thoroughly when the soil is completely dry, typically every two weeks during the active growing season, and reduce watering in the winter to prevent root rot. This cultivar is not frost-tolerant and should be protected from freezing temperatures. Fertilize lightly during the growing season to support flowering and growth.
