[Cultivation]
Propagate from seed.
In cold regions it is treated as an annual sown in spring, and elsewhere as an annual sown in autumn.
It dislikes transplanting, so sow directly where it is to grow, or sow in plastic pots and then plant out.
It prefers sunny, well-drained soil.
In regions with hot summers, it is best to let it spend the summer in cool partial shade.
For potted plants, water thoroughly when the soil surface dries; for plants in the ground, rainfall is sufficient.
If fertilizer is applied at planting, no further fertilizer is particularly needed.
Pests and diseases include powdery mildew and aphids.
