Huernia hystrix is a striking, low-growing succulent native to southern Africa. Its name “hystrix” means porcupine, referring to the small, soft spines that cover its angular, upright stems. While its foliage alone is sculptural and eye-catching, this plant truly comes alive when it blooms: exotic, star-shaped flowers in shades of cream and maroon, often with bold striping or mottling, appear close to the base of the stems. Like many in the stapeliad group, the flowers have a faintly musky scent designed to attract pollinators—making them a fascinating conversation starter in any collection.
