Datura wrightii or Sacred Datura is the name of a poisonous perennial plant and ornamental flower of southwestern North America. It is sometimes used as a hallucinogen. Datura wrightii is classified as a deliriant and an anticholinergic.[1]
It is a vigorous herbaceous perennial[2] that grows 30 cm to 1.5 m tall and wide.[3] 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 (8 inches) long, often tinted purple, especially at the margin. There are five narrow points spaced symmetrically around the rim. It can bloom from April to October.[2] In clear weather, flowers open at nearly full dark and wither a few hours after sunrise the following morning; 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, which opens when fully ripe
