Growing notes
- Native to the Cape Floristic Region of South Africa — naturally occurs in mountain gullies in part shade
- Tolerates more shade than most pelargoniums — useful as a fragrant ground cover under trees
- Edible leaves — used to flavour syrups and ice cream, with a clean peppermint flavour
- Frost-tender — needs winter protection below zone 9
- Not reliably hardy outdoors in Canada — Canadian zone values shown represent the system maximum and do not imply garden cultivation north of the warmest coastal pockets.
