Huernia hystrix

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.

Light: Bright gentle light to full sun. Protect from intense afternoon sun in hot climates.
Temperature: Warmth-loving (65–90°F). Protect from temps below 50°F.
Humidity: Low to moderate. Prefers dry air and good ventilation.
Water: Water thoroughly when soil is dry, then allow to drain completely. Keep almost dry in winter.
Soil: Very well-draining cactus/succulent mix with added perlite or pumice.
Fertilizer: Feed lightly in the growing season with diluted cactus fertilizer.

How to grow Huernia hystrix indoors:
Place in a sunny window or under strong grow lights. Avoid overwatering, especially in cooler months. Use a pot with drainage holes and a gritty mix to prevent root rot. Distilled or filtered water is best if your tap water is mineral-heavy—Hetch Hetchy water is generally fine.

How to grow Huernia hystrix outdoors in the Bay Area:
Perfect for summering outdoors in bright gentle light. Protect from heavy rain and bring inside before temperatures drop below 50°F. Works beautifully in small pots on sunny patios or in a mixed succulent display.

Pet safe: No—likely toxic if ingested
Difficulty: Easy to intermediate. Thrives with bright light, careful watering, and excellent drainage.
