Datura wrightii aka Sacred Thorn Apple

Datura wrightii, also known as sacred datura or angel trumpet, is a poisonous perennial plant species and ornamental flower in the Solanaceae family. It is native to the Southwestern United States and northwestern Mexico and can grow up to 1.5 meters tall and wide, with broad leaves and sweetly fragrant white flowers that resemble trumpets up to 20 cm long. However, all parts of the plant contain dangerous levels of anticholinergic tropane alkaloids that can be fatal if ingested by humans, livestock, or pets. As a result, it is prohibited in some areas to buy, sell or cultivate Datura plants. Despite its toxicity, it is sometimes used as a hallucinogen due to its psychoactive alkaloids. The plant is also considered weedy in some parts of the west due to its sprawling growth habit.
