Datura is a vigorous herbaceous perennial that grows 30 cm to 1.5 m tall and wide. The leaves are broad and rounded at the base, tapering to a point, often with wavy margins. The flowers are the most striking feature, being sweetly fragrant white trumpets up to 20 cm (7.9 in) long, sometimes tinted purple, especially at the margin. Five narrow points are spaced symmetrically around the rim. The plants often can be seen as ground vines inhabit, growing close to the ground and spreading in a very exposed environment with full direct sunlight. D. Wrightii blooms from April through October. In clear weather, flowers open in the morning and evening and close during the day's heat (depending on water availability); in cloudy weather, they may open earlier and last longer.
The seeds are borne in a spiny, globular capsule 3 to 4 cm in diameter, opening when fully ripe.
Datura wrightii is found in northern Mexico and the adjoining southwestern U. S. states, as far north as southern Utah, in open/disturbed land and along roadsides with well-drained (sandy) soils. However, it is perhaps most naturally abundant in the region of Southern California. It is also commonly planted as an ornamental, especially in xeriscapes, due to its ruderal characteristics.
All parts of Datura plants contain dangerous levels of anticholinergic tropane alkaloids and may be fatal if ingested by humans, livestock, or pets. It is prohibited to buy, sell, or cultivate Datura plants in some places. Unlike other types of datura, the roots are considered the most potent and alkaloid-rich part of this species.
