Datura is a very showy plant, although it is considered a weedy species found growing in disturbed areas. It has very large, white (sometimes tinged purple), funnel-shaped flowers that bloom in the late afternoon and evening, and close in the morning. Fragrant flowers are pollinated at night by hawk moths. Hawk moths hover like. hummingbirds and unfurl a very long proboscis into the floral tube to get the nectar.  It contains numerous poisonous alkaloids including atropine, hyoscyamine, and hyoscine and every year these produce a number of deaths in the United States.
