Fun Facts
- 🌱 The 'Sundial' name refers to the flower's behavior of closing petals at night and in cloudy conditions, functioning as a natural indicator of sunny weather—similar to how sundials work.
- 🌱 Osteospermum is native to South Africa and the Canary Islands, making it exceptionally drought-tolerant compared to many garden ornamentals.
- 🌱 Unlike many daisies, Osteospermum flowers have a unique mechanism where the outer ray florets often display different colors than the inner disk florets, creating the striking two-tone effect.
