Which flower did Georgia O'Keeffe paint in a 1936 work titled Jimson Weed?

Georgia O'Keeffe’s 1936 work Jimson Weed depicts jimson weed, a flowering plant also known as Datura.

The painting presents a large white flower against a dark background. O'Keeffe repeatedly enlarged flowers so that viewers would confront their structure and details rather than treating them as minor decorative motifs.

Jimson weed is a plant in the nightshade family. Its trumpet-shaped flowers can be white or pale violet, and the plant is toxic. The painting is often discussed alongside O'Keeffe’s other flower images, but it is distinct from her 1932 painting commonly known as Jimson Weed/White Flower No. 1.

The title “Jimson Weed” can cause confusion because O'Keeffe made more than one work involving the plant. The 1936 painting is a specific later work, while the famous 1932 flower is usually identified by its longer title.
