The Rainbow Hedgehog Cactus (Echinocereus rigidissimus) is a rare and visually striking cactus known for its vibrant, multicolored spines that create a rainbow effect along its cylindrical stem. This compact species can grow up to 12 inches tall and produces large, showy pink or magenta blooms in late spring to early summer. Its unique coloration and stunning flowers make it a prized choice for collectors and enthusiasts. Each plant is one of a kind, with slight variations in color and form. This cactus thrives in full sun to partial shade and requires well-draining soil with minimal watering—allowing the soil to dry completely between waterings prevents root rot. It prefers warm temperatures but can tolerate brief drops to 10°F when kept dry. Shipped in a 4-inch nursery pot, each plant is carefully packaged to ensure it arrives healthy. Due to its rarity, availability is limited, making this a must-have addition to any plant collection.
