Fun Facts

- 🌱 Oscularia deltoides produces a distinctive fragrance reminiscent of old-fashioned rose geraniums, releasing scent especially in warm, dry conditions.
- 🌱 The pink coloration that intensifies in bright light and cooler temperatures is a stress response (anthocyanin production) that actually indicates the plant is thriving, not suffering.
