It also spreads readily from self-sown seed.
It dislikes heat and humidity, so it is sometimes treated as a biennial.
It prefers a sunny, well-drained soil.
It dislikes excess moisture, so for potted plants, water thoroughly only after the soil has dried completely; for plants in the ground, rainfall is sufficient.
For plants in the ground, fertilizer is not particularly necessary if basal fertilizer is applied; for potted plants, place slow-release fertilizer on the soil in spring and autumn.
There are no particular pests or diseases.
