Which flower is the subject of Georgia O'Keeffe's 1936 painting Jimson Weed?

Jimson weed is the flower subject of Georgia O'Keeffe's 1936 painting Jimson Weed.

The work is formally titled Jimson Weed/White Flower No. 1 and shows a large white jimson-weed blossom against a dark background. O'Keeffe often enlarged flowers so that viewers had to confront their shapes, folds, and tonal changes at close range.

The painting became especially famous when it sold at auction in 2014 for $44.4 million, then a record price for a work by a female artist. Its auction fame sometimes causes people to confuse it with O'Keeffe paintings of poppies, irises, or calla lilies.

Jimson weed is also called Datura stramonium and has toxic properties. The botanical subject and the painting's title are related, but the artwork is not a botanical illustration or a claim that the plant is safe to handle.
