What was the title of Georgia O'Keeffe's 1932 painting that became famous for its enlarged white flower?

Georgia O’Keeffe’s 1932 painting of an enlarged white jimson weed flower is titled Jimson Weed/White Flower No. 1. The work presents a single trumpet-shaped blossom at a monumental scale.

O’Keeffe frequently enlarged flowers so viewers had to confront their structures rather than glance past them as small garden details. Jimson Weed/White Flower No. 1 uses a narrow palette of white, green, and dark background tones, creating a stark, highly controlled image.

The painting is often referred to simply as Jimson Weed, but its full title identifies it as White Flower No. 1. Jimson weed is the common name for a poisonous plant in the genus Datura. O’Keeffe’s flower paintings are sometimes interpreted symbolically, but she repeatedly emphasized close looking at the forms themselves.
