How to Grow African Daisy
Dimorphotheca sinuata
African Daisy is a tender annual for the sunniest, driest spot in the garden. Sow indoors in early spring and plant out after all frost risk has passed. Full sun is non-negotiable — flowers close in shade or cool weather. Deadhead spent blooms regularly to keep flowers coming from early summer right through to autumn. No staking needed; very little feeding required. Perfect for hot, dry borders, gravel gardens, and containers.
When to Start
Start seeds indoors 5 weeks before your last frost date. Transplant outdoors once night temperatures stay above 10°C and soil has warmed to at least 12°C.

Care Essentials
- Rarely — a low-fertility plant. One light application of balanced fertiliser at planting is enough; overfeeding produces foliage at the expense of flowers.
- Flowers close in the evening and on overcast days — this is normal behaviour. Full sun is essential for good flower display. Excellent for hot, dry, sunny borders.
