How to Grow and Care

You can grow Daturas inside or outside in a pot, or simply spread seed with a light coat of sand outside in a sunny location. They are usually planted annually from the seed, but with care, plants can be overwintered. Most species are suited to be planted outside or in containers.

Daturas do best in full or close to full sun. The more light, the better in general.

Datura is a truly tropical species that does not take kindly to colder temperatures. Cold drafts are likely to result in leaf drop, and frost will kill it.

In containers, they should have porous, aerated potting soil with adequate drainage.

Regular watering during the growing season to keep the soil moist at all times but not soaking. During the winter, reduce watering somewhat, but never let the soil completely dry out.

Feed weekly with a weak liquid fertilizer that encourages blooming. See more at How to Grow and Care for Daturas.


It is native to the southwestern United States, Central, and South America.
