What was the title of Georgia O'Keeffe's 1932 painting that became a famous flower work?

Georgia O'Keeffe's 1932 painting is titled Jimson Weed/White Flower No. 1.

The work presents a large white jimson weed flower against a dark background. O'Keeffe enlarged floral forms so that viewers had to confront their structure, curves, folds, and tonal changes at close range. This approach helped make flowers among the most recognizable subjects in her art.

The painting is also notable for its later market history. In 2014, it sold at auction for $44.4 million, setting a record at the time for the most expensive painting by a female artist.

The title is sometimes shortened to Jimson Weed, but the full catalog title includes White Flower No. 1. It should also not be confused with O'Keeffe's Black Iris or Red Canna paintings, which belong to different flower series.
