Stapelia

[3][4] The flowers of certain species, most notably Stapelia gigantea, can reach 41 cm (16 inches) in diameter when fully open.

The hairy, oddly textured and coloured appearance of many Stapelia flowers has been claimed to resemble that of rotting meat, and this, coupled with their odour, has earned the most commonly grown members of the genus Stapelia the common name of carrion flowers.

Such odours serve to attract various specialist pollinators including, in the case of carrion-scented blooms, blow flies of the dipteran family Calliphoridae.

Stapelia are good container plants and can grow well under full sun and light to moderate watering.
