Datura–often called angel’s trumpet– is an annual or short-lived perennial that bears stiking trumpet-shaped flower. Flowers are commonly white and up to 8 inches (20cm) long and nearly just as wide. Flowers appear in mid to late summer; they are followed by large spiny fruits which are poisonous.
Datura’s fragrant flowers appear on trailing stems surrouned by elliptical or oval grayish green leaves. Datura can be trained up on supports or a trellis.
Once species Datura wrightii is grown for its fragrant flowers. Another species D. stramonium is commonly called jimson weed; it is a common North American weed, especially in dry, warm regions.
Datura flowers look very much like the flower of Brugmansia, also commonly called angel’s trumpet. Brugmansia differs from Datura in that it is woody; the Brugmansia genus lncludes shrubs and trees.
Datura is a genus of eight species of annuals and short-lived perennials native to southern North America.
All parts of Datura plants are poisonous.
