Origins and peculiarities of osteospermum
Theosteospermum, also known as "Cape daisy", "African daisy" or even "rain marigold" is a plant belonging to the Asteraceae family and native to the African continent.
This perennial stands out for its remarkable flowering, rich in color, which extends from May to October (!). Its foliage is dense and has good hold. There are 4 varieties of osteospermum: osteospermum ecklonis "Blue Streak", the osteospermum "Buttermilk", the osteospermum "Whirlygig" and l'osteospermum "Pink Whirls". Each variety produces beautiful flowers similar to daisies. White, purple, pink, orange, salmon, lavender, blue, yellow or purple ... there is something for everyone!
One of the peculiarities of the osteospermum is that its flowers love the sun and the light; in fact, they close in the evening, as soon as daylight begins to decline.
The osteospermum is a flowering plant that it is also possible to cultivate:
- in the ground, especially in rock gardens or borders;
- but also in pots or planters to decorate terraces and balconies;
- by the sea, because the plant appreciates sandy soils and does not allow itself to be disconcerted by the spray.
Planting of osteospermum
The osteospermum is a plant which is cultivated easily: indeed it likes as well in pot as in full ground and displays a good tolerance to drought.
In terms of location, a light and well-drained soil will be enough for its good development, even if, in view of its origins, it has a little preference for sandy soils. Likewise, the osteospermum needs to be exposed to the sun and heat to flourish and flower from May to October.
For optimal flowering, be sure to plant your osteospermum in spring, between March and May. Plan two plants of osteospermum for planting in a planter, and three plants for a large pot. Remember to moisten the clods well before planting them.
Maintenance of the osteospermum
The osteospermum is one of the easiest plants to cultivate and maintain:
- In hot weather, regular watering will allow the osteospermum to cool down. In general, remember that when its stems begin to fall down, it is because the plant is thirsty and it is necessary to water it!
- We must also remember to rid the plant of its faded flowers to stimulate the growth of new flower buds.
- For species planted in pots, a fertilizer supply will be welcome in summer to feed the abundant vegetation of the plant (the fertilizer must be rich in potassium and phosphorus). The osteospermum is not a big fan of cold, so be sure to tuck in your pots before it starts to freeze.
Diseases and pests of osteospermum
Aphids and downy mildew are the main enemies of osteospermum. For aphids, a simple biological treatment such as the use of ladybugs makes it easier to get rid of them.
Similarly, a little powdery mildew can appear if the watering is directed directly on the foliage. Watering the plants generally is enough to avoid this.
