Genus guide
Caralluma — 6 species
Part of the Hoyas & relatives family (Apocynaceae)
Caralluma is a drought-adapted succulent genus native to arid regions of Africa, India, and the Mediterranean, including species such as Caralluma europaea and Caralluma acutangula. The stems are angular and cactus-like, carrying small star-shaped flowers that can smell unpleasant at close range. Provide full sun to bright indirect light — six to eight hours daily is ideal — and water sparingly, allowing the growing medium to dry out completely between waterings to avoid rot. All Caralluma species are toxic to cats and dogs and must be kept away from pets.
