Fun Facts
- 🌱 The odor of Stapelia flowers mimics rotting flesh, deceiving flies into pollinating the plant by laying eggs on the flower as if it were carrion; this deception strategy is called sapromyophily.
- 🌱 Some Stapelia species produce flowers with a hairy texture that further mimics decomposing flesh, enhancing the illusion for insect pollinators.
- 🌱 Despite the unpleasant odor, Stapelia has been cultivated as an ornamental plant for over 300 years, with the first European cultivation recorded in the 1600s.
