5. Star Flowers
These succulents grow amazing hairy flowers that give off the smell of rotting flesh. They blooms are very big and the larger the species the more pungent the scent. The hairs on the flower are there to resemble a layer of mould that grows on rotting meat.
Blow flies act as pollinators and a lot of flies will actually lay their eggs inside the flower, as they would with a rotting carcass.
