Full details
The Osteospermum African Sun from Thompson & Morgan is ideal for gardeners looking to add vibrant, golden-yellow and orange bi-colored blooms to their outdoor spaces. These plants excel in warm, dry environments and are perfect for patio containers, rockeries, or sunny garden borders. While they are highly attractive to pollinators, users should note that they require careful temperature management during the early germination phase and must be fully protected from frost until the warmer months arrive.

FAQs
When is the best time to sow these seeds?
Sow your seeds indoors between February and May.
Do these plants need full sun?
Yes, they thrive in full sun and perform best in warm, dry conditions.
How far apart should I plant the seedlings?
Space your plants by at least 30cm to allow for their mature spread.
Are these plants hardy?
No, they are not frost-hardy and must be protected from cold temperatures until all risk of frost has passed.
Can I grow these in rockeries?
Yes, they are well-suited for rockeries and alpine settings provided the drainage is good.
How long until I see flowers?
While germination takes 10-14 days, the time to bloom depends on local conditions and transplant timing, typically occurring in the summer.
Troubleshooting
Seeds failing to germinate
Ensure the temperature is maintained at 15C and verify that the seeds are not covered too deeply, as they require light to germinate.
Seedlings becoming leggy
This often indicates insufficient light; move the seedlings to a brighter location immediately after germination.
Root rot or stunted growth
The soil may be too damp. Ensure your containers or beds have excellent drainage and allow the surface to dry slightly between waterings.
Pros and Cons
Pros
- High aesthetic appeal with vibrant color palette
- Excellent for container and patio gardening
- Supports local biodiversity by attracting pollinators

Cons
- Requires specific temperature control (approx 15C) for germination

- Requires well-drained soil to prevent waterlogging
Setup, Compatibility & Care
To start your seeds, sow them between February and May in a propagator at approximately 15C. Lightly cover with vermiculite and ensure the compost remains moist but not saturated. Do not exclude light, as it is necessary for the germination process, which typically takes 10 to 14 days. Once seedlings are large enough to handle, move them into 7.5cm pots. It is critical to gradually acclimatize the plants to outdoor conditions before planting them 30cm apart in rich, well-drained soil only after the final frost has passed.
