Description

edit

Growing to 10 cm (3.9 in) tall by 50 cm (20 in) broad, it is a leafless succulent perennial with cactus-like toothed stems, and highly variable, star-shaped, off-white or yellow flowers strongly speckled with maroon, up to 8 cm (3.1 in) in diameter. The flowers may show regular (banded) markings, or irregular ones. They have five pointed or blunt lobes surrounding a central, pentagonal annulus (corona).[4] The flowers may have a faint carrion smell to attract potential insect pollinators.[5]

Cultivation

edit

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.[5] 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.[6][7]
