Origin of Name

The genus name "Astrophytum" is derived from the Greek words "astron," meaning star, and "phyton," meaning plant, referring to the star-like shape of the cacti in this genus. "Capricorne" originates from Latin, meaning "goat's horn," describing the curved shape of the plant's spines that resemble the horns of a goat. The variety name "crassispinum" comes from Latin words "crassus," meaning thick, and "spinum," meaning spine, highlighting this variety's notably thick and robust spines.

Technical Description of Plant

Astrophytum capricorne var. crassispinum is celebrated for its spherical to slightly elongated green body, which can reach up to 6 inches in diameter. The surface is adorned with white, woolly areoles that contrast beautifully against the dark green cactus flesh. This variety is distinguished by its dense, long, and thick yellow to dark brown spines that curve around the plant's body, providing a distinctive and dramatic appearance. During the summer months, it blooms with large, yellow flowers that add to its ornamental value.

Origin of Plant

Native to the arid regions of Northern Mexico, Astrophytum capricorne var. crassispinum has adapted to survive in harsh environments with infrequent rainfall. Its robust spines offer protection from herbivores, while its ability to store water allows it to thrive in extreme conditions.

Conservation Status

Like many cacti native to Mexico, Astrophytum capricorne var. crassispinum faces threats from habitat loss due to agricultural expansion and urbanization, as well as from illegal collection for the horticultural trade. While not currently listed as endangered, conservation efforts focus on habitat preservation and promoting responsible cultivation and trade practices.

Care Instructions

Astrophytum capricorne var. crassispinum requires bright, direct light to flourish and prefers well-draining soil. Water moderately during the growing season, allowing the soil to dry out completely between waterings, and reduce watering significantly during the winter to prevent root rot. This cactus is cold-tolerant to a degree but should be protected from frost. Fertilize sparingly with a cactus-specific fertilizer during the active growing season to support health and blooming.
