Datura

datura, (genus Datura), also called thorn apple, genus of about nine species of poisonous flowering plants in the nightshade family (Solanaceae). Several Datura species are collected for use as drugs, and others are cultivated for their showy flowers. Many are considered weeds in warm parts of the world and commonly grow along roadsides and other disturbed habitats. Datura species are often confused with members of the related genus Brugmansia, which features a number of ornamental trees and shrubs known as angel’s trumpets.
