Deadhead flowers regularly by pinching or cutting just below the flower head to encourage continuous blooming throughout the season. Cut flowers last 7-10 days in a vase; harvest in early morning when stems are hydrated. Remove entire flower stems at the base rather than just removing petals.
Fun Facts
- 🌱 South African daisies are heliotropic, meaning their flowers follow the sun throughout the day, opening wider in sunny conditions and closing partially on cloudy days or at night.
- 🌱 The genus name 'Osteospermum' derives from Greek words meaning 'bone seed,' referring to the hard, bony seeds these plants produce.
- 🌱 These flowers were originally collected by European botanists in South Africa during the 18th and 19th centuries and have become beloved worldwide, particularly in Mediterranean and temperate gardens.
