About
Orbea variegata, also known as the star flower, carrion flower, starfish cactus and toad cactus, is a species of flowering plant in the family Apocynaceae that is native to the coastal belt of the Western Cape, South Africa, growing actively during the winter rainfall season. It is an invasive species in southern Australia.
How to grow it
This plant is popular in cultivation, and is often sold under its former name Stapelia variegata. It has many common names, including starfish plant, starfish cactus, carrion cactus, carrion flower, toad cactus, toad plant. It is not closely related to the true cactus family. When grown as an ornamental plant in temperate zones it requires protection, as it does not tolerate freezing temperatures. It is best grown under glass, in similar conditions to cacti.
In the UK it has gained the Royal Horticultural Society's Award of Garden Merit.
Where it grows
Native to southern Africa, it thrives at altitudes between 0 and about 1,000 meters. It grows on gently sloping, but rarely steep, rocky slopes, sometimes under bushes, but also in locations with more or less full sun exposure.
