What flower is shown in Georgia O'Keeffe's famous 1936 painting Jimson Weed?

The flower shown in Georgia O'Keeffe's famous 1936 painting Jimson Weed is jimson weed.

Jimson Weed, also known as White Flower No. 1, presents a large, white, trumpet-shaped jimson weed blossom against a dark background. O'Keeffe painted the work in 1932, although the title is often discussed in connection with her broader series of flower paintings from the 1930s.

The plant is also known as Datura stramonium and has a long history of toxic use. O'Keeffe was interested in its dramatic form and pale petals rather than presenting it as a botanical or medicinal illustration. Her enlargement of the flower encourages viewers to look closely at its folds and internal structure.

The painting is sometimes mistakenly identified as a lily, poppy, or hollyhock because O'Keeffe painted allusions to many flowers. Its trumpet form and title identify it specifically as jimson weed. The work became one of her most valuable paintings after its 2014 auction sale.
