Echinocereus coccineus, commonly referred to as the claret cup cactus or scarlet hedgehog cactus, is a hardy and visually captivating species native to the arid and semi-arid regions of the southwestern United States and northern Mexico. This low-growing, clump-forming cactus is characterized by its cylindrical stems, which are densely covered in spines and often form large mounds that can contain dozens of individual stems. What makes Echinocereus coccineus especially remarkable is its dazzling floral display—during late spring to early summer, it produces brilliant scarlet to deep red, funnel-shaped flowers that contrast vividly with the plant’s spiny green stems. These flowers are not only eye-catching but also adapted to attract hummingbirds, which serve as their primary pollinators. The flowers are followed by small, greenish-red fruits that are edible and enjoyed by desert wildlife. This species is highly tolerant of heat, drought, and cold, often found in rocky canyons, desert slopes, and pinyon-juniper woodlands, thriving in elevations ranging from low desert valleys to mountainous regions. Because of its vibrant blooms, resilience, and ease of cultivation, Echinocereus coccineus is a favorite in native plant gardens, rock gardens, and xeriscapes, offering ecological value and seasonal bursts of color in harsh environments.
