Fun Facts
- 🌱 Stapelia variegata's common name 'Starfish Flower' refers to the shape of its blooms, while another common name 'Carrion Flower' comes from the faint odor of decaying meat it produces to attract fly pollinators—nature's clever trick for reproduction.
- 🌱 The plant's genus Stapelia contains about 50 species, all native to southern Africa, and the family Apocynaceae is renowned for producing unusual and aromatic flowers.
- 🌱 In their native South African habitat, Stapelia flowers are pollinated primarily by carrion flies attracted to the scent; interestingly, the flower's mottled coloration mimics rotting flesh, adding a visual deception to complement the olfactory one.
