Caralluma acutangula is a rare and fascinating succulent native to arid regions of the Arabian Peninsula and northeastern Africa. Known for its striking star-shaped flowers and angular, fleshy stems, this species is highly prized by collectors of unusual succulents and caudiciforms.

The plant forms clumps of upright, quadrangular stems with toothed angles, giving it a sculptural, geometric appearance. In summer, it produces small, deep reddish-purple flowers in clusters near the tips of the stems. These blooms are often visited by flies and other pollinators attracted to their distinctive appearance.

Caralluma acutangula thrives in full sun to partial shade and well-draining, sandy or gritty soil. Like many arid-adapted succulents, it requires minimal watering and excellent drainage to prevent rot. It’s best suited for containers, rock gardens, or dry indoor settings.

Uncommon in cultivation, this species makes an excellent choice for enthusiasts seeking to grow something truly unique and visually intriguing.

Can I grow Caralluma acutangula from seeds?

Yes, it can be grown from seeds, although germination can be slow and irregular. Sow the seeds on the surface of a well-draining succulent mix, keep them warm and lightly moist. Germination may take several weeks.

How big does Caralluma acutangula get?

This species remains compact, typically growing to about 15–30 cm tall. It spreads gradually through branching stems and forms small clumps over time.

Is Caralluma acutangula hard to care for?

Not at all, provided it is kept dry and warm. It’s a low-maintenance plant that thrives on neglect—perfect for succulent collectors with limited watering schedules.
