Datura is a genus of nine species of poisonous vespertine flowering plants belonging to the family Solanaceae. They are commonly known as daturas, but also known as devil's trumpets, not to be confused with angel's trumpets, its closely related genus Brugmansia. They are also sometimes called moonflowers, jimsonweed, devil's weed, hell's bells, thorn-apple, and many more. Its precise and natural distribution is uncertain, owing to its extensive cultivation and naturalization throughout the temperate and tropical regions of the globe. Its distribution within the Americas and North Africa, however, is most likely restricted to the United States, Mexico and Southern Canada in North America, and Tunisia in Africa where the highest species diversity occurs. All species of Datura are poisonous, especially their seeds and flowers. Some South American plants formerly thought of as Datura are now treated as belonging to the distinct genus Brugmansia (Brugmansia differs from Datura in that it is woody, making shrubs or small trees, and it has pendulous flowers, rather than erect ones). Other related taxa include Hyoscyamus niger, Atropa belladonna, Mandragora officinarum, Physalis, and many more.
