Fun Facts
- 🌱 African daisies (Osteospermum) are native to South Africa and respond to sunlight by opening and closing their petals—they typically close at night or on cloudy days, earning them the nickname 'sunlight sleepers.'
- 🌱 The 'Sunny Side Up' cultivar is specifically bred for its cheerful bicolor yellow and orange petals with dark centers, resembling a fried egg, which inspired its whimsical common name.
- 🌱 Despite their tender perennial nature in warm climates, African daisies can be successfully grown as annuals in cooler regions, treated much like petunias or marigolds.
