Datura is a genus of nine species of vespertine flowering plants belonging to the family Solanaceae. They are known as angel's trumpets, sometimes sharing that name with the closely related genus Brugmansia, and commonly as daturas. They are also sometimes called moonflowers, one of several plant species to be so. 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 Tunisia, where the highest species diversity occurs.
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 genera include Hyoscyamus and Atropa.
