Fun Facts
- 🌱 The name 'Osteospermum' comes from Greek words 'osteon' (bone) and 'sperma' (seed), referring to the hard, bone-like seed structure.
- 🌱 African Daisies exhibit nyctinasty, meaning their flowers close at night and open again in daylight—a behavior that helps protect pollen and reduce water loss.
- 🌱 The 'African Sunrise' cultivar displays warm gradient colors ranging from coral-pink to yellow-orange, mimicking a sunrise across the sky, making it particularly photogenic for gardens.
