Osteospermum, also known as the African daisy, is native to the regions of South Africa, which explains its resilience and love for the sun. Its wide array of colours, ranging from purple and orange to white, forms a multi-coloured carpet in any garden setting. Whether in a container, as part of a border, or in seasonal flowerbeds, osteospermum is a true eye-catcher. However, this plant is a bit particular about where it thrives. Let’s explore the best locations for planting osteospermum and which plants pair well for a beautiful ground cover.
Where to Plant Exotic and Familiar Osteospermum?
Osteospermum is a sun lover, and a shady location is not suitable for this plant. If planted in the shade, osteospermum will struggle to thrive and may fail to produce its vibrant flowers. Hybridized cultivars of osteospermum may be slightly more adaptable to different conditions, but it still requires sunny exposure to bloom to its fullest potential.
When deciding where to plant osteospermum, choose a well-drained soil with good drainage and constant humidity. Though osteospermum is quite rustic, it still requires moist soil until the plant is well-established. Once the spring weather improves, you should be ready to plant osteospermum, as the warm temperatures will trigger its impressive flowering.
For seed planting, simply press the soil and monitor the germination process. When planting cultivars, space the stems 2.5 to 5 cm apart. Regular watering and the addition of organic matter will help the plant establish itself, though it is crucial to ensure the soil doesn’t dry out.
How to Care for Potted Osteospermum?
Growing osteospermum in a pot requires extra attention to soil moisture. During periods of drought, make sure the soil does not dry out completely. For optimal growth, apply fertilizer every two weeks to provide the nutrients it needs. Osteospermum can survive winter if kept in a sheltered location, protected from wind and frost. However, taking cuttings in the fall is a great way to ensure flowers for the next winter season.
Though osteospermum doesn’t require extensive pruning, it benefits from regular deadheading (removal of dead flowers) to encourage continuous blooming. Keep an eye out for pests such as whiteflies and aphids, which can damage the plant’s leaves and petals. Regularly inspecting your osteospermum will help you catch these issues early. One of the more serious problems is gray mold, which occurs when there is insufficient air circulation and excessive humidity around the plant.
Which Plant to Associate with Osteospermum?
The unusual colours of osteospermum make it a striking and standout plant in any garden, but this can make it difficult to pair with other plants. However, there are some plants that complement osteospermum beautifully.
- Baby’s breath, daylilies, and creeping phlox paniculata are excellent companions, as their more subdued colours let osteospermum take center stage.
- Euphorbia, verbena, and dipladenia are also good companions, as they add height and serve as a screen, allowing osteospermum’s vibrant colours to shine.
As for propagation, osteospermum naturally reseeds itself, which is common among the hundred or so varieties of this plant. You can propagate osteospermum by sowing seeds or allowing the plant to self-sow.
By choosing the right planting location and selecting complementary plants, you can enjoy the beauty of osteospermum in your garden while ensuring it thrives and grows healthily.
