[Cultivation]
Propagate from seed or by cuttings.
It can overwinter outdoors in regions without frost.
It prefers a sunny, airy, well-drained sandy soil.
Avoid cold winter winds.
It dislikes heat and humidity, so it is best to move potted plants during the rainy season and summer to a cool, airy place in partial shade where rain does not reach them.
For potted plants, in spring and autumn water thoroughly when the soil surface dries, and keep them slightly on the dry side in midsummer.
For plants in the ground, rainfall is sufficient.
In spring and autumn, apply slow-release fertilizer placed on the soil.
Remove spent flowers promptly.
Cutting back before summer to improve ventilation makes it easier to get through the summer.
Aphids can occur.
