At a glance
Osteospermum is sensitive to waterlogged roots, so planting in heavy clay soil or containers without drainage holes will likely cause root rot and a rapid decline in plant health.

Step-by-step planting
Growing Osteospermum from seed is straightforward once you understand a few preferences this plant brings from its South African roots.
-
1
Choose the Right Timing
Start Osteospermum seeds indoors 6 to 8 weeks before your last expected frost date, or sow directly outdoors once nighttime temperatures stay consistently above 50 degrees Fahrenheit.
-
2
Prepare a Well-Draining Mix
Use a light seed-starting mix or combine potting soil with perlite at roughly a 3 to 1 ratio, because Osteospermum germination is far more reliable when roots never sit in soggy conditions.
-
3
Sow at the Right Depth
Press seeds gently into the surface of your mix and cover with just enough soil to block light, about 3 to 5 millimeters deep, since light exclusion during germination tends to improve sprouting consistency.
-
4
Keep Soil Warm and Moist
Maintain a soil temperature between 60 and 70 degrees Fahrenheit and mist the surface regularly to keep it evenly moist but not wet, as cold or erratic moisture conditions can significantly slow or prevent sprouting.
-
5
Transplant with Care
Once seedlings have two sets of true leaves and outdoor conditions are settled, harden them off over 7 to 10 days by gradually increasing their outdoor exposure before transplanting into their final spot.
-
6
Plant in Full Sun
Choose a location that receives at least 6 hours of direct sun daily, because African daisy full sun flowers are more prolific and the plants stay more compact compared to those grown in partial shade.
-
7
Deadhead for Continued Blooms
Pinch or snip off spent blooms every few days during peak season to encourage the plant to redirect energy into new flower production rather than setting seed.

Germination
Germination rates vary depending on climate, soil conditions, and care. Seeds perform best when planted in the right season at the correct temperature, with consistent moisture and adequate light. We take quality seriously and each batch is tested before packaging. If you have concerns about your seeds, reach out and we will do our best to help.
Frequently asked
Questions about Osteospermum Seeds – Osteospermum ecklonis
How long do Osteospermum seeds take to germinate?
Osteospermum germination typically occurs within 10 to 21 days under warm, consistent conditions, though this range can shift depending on your soil temperature, moisture levels, and the time of year you are sowing. Seeds started in cool or fluctuating conditions will often take longer, and some may surprise you by sprouting well past the expected window. Providing steady warmth around 65 degrees Fahrenheit gives you the most predictable results.
Can African daisies grow in containers?
African daisy container plants perform very well as long as the pot has adequate drainage holes and you resist the urge to overwater. Choose a container at least 8 to 10 inches deep to give the roots room to develop, and use a gritty, well-draining potting mix rather than a dense moisture-retaining blend. Container-grown plants may need more frequent watering in peak summer heat, but always let the top inch of soil dry out between waterings.
Are Osteospermum plants toxic to pets?
Osteospermum is not widely listed among plants known to cause serious toxicity in cats or dogs, but it also has not been extensively studied, so caution is reasonable if you have pets that chew on plants. The ASPCA does not currently list it as a confirmed toxic species, but every animal responds differently, and ingestion of plant material in quantity can cause mild digestive upset in some pets. If you have concerns, placing containers out of reach or fencing off garden beds is a practical precaution.
Do African daisies come back every year?
In USDA zones 9 through 11, Osteospermum ecklonis can behave as a short-lived perennial and may return season after season given mild winters and good drainage. In cooler climates, including most of zones 4 through 8, it is typically grown as an annual, completing its life cycle in a single season. Some gardeners in borderline zones have success overwintering plants in a protected spot or bringing container plants indoors before the first hard frost.
When should I start Osteospermum seeds indoors?
Starting seeds indoors 6 to 8 weeks before your last average frost date gives seedlings enough time to establish without becoming rootbound or leggy before they can go outside. In most of the northern United States, this means starting in late February or March. Growers in warmer climates can often direct sow outdoors in late winter when soil temperatures begin to climb.
How much sun do African daisies need?
African daisies need full sun, ideally at least 6 hours of direct sunlight per day, to flower well and maintain a tidy, upright habit. Plants grown in partial shade tend to stretch toward the light, produce fewer blooms, and are more prone to fungal problems due to reduced air movement around the foliage. If you are gardening in a very hot climate, a spot with bright morning sun and some afternoon shelter can help prolong bloom time into summer.
Why do my Osteospermum flowers close at night?
Osteospermum flowers are nyctinastic, meaning they open and close in response to light levels, which is a completely normal and healthy behavior for this species. The blooms open with the morning sun and typically close in the late afternoon or when skies turn overcast. This trait is part of the plant's natural biology and does not indicate any problem with care or health.
