Datura

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. They are also sometimes called Moonflowers, one of several plant species to be so. Datura's 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, however, is most likely restricted to the United States and Mexico, where the highest species diversity occurs.

Some South American plants formerly thought of as Daturas 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 in that it has pendulous flowers, rather than erect ones). Other related genera include Hyoscyamus and Atropa.
