What was the title of Georgia O'Keeffe's 1932 painting that became her most expensive work sold at auction in 2014?

Georgia O'Keeffe's 1932 painting Jimson Weed/White Flower No. 1 became her most expensive work sold at auction in 2014.

The painting presents a single large white jimson weed flower against a pale background. O'Keeffe enlarged flowers so viewers had to confront their structures, a strategy that helped make her flower paintings some of the most recognizable images in American modernism.

At a Sotheby's auction in New York on November 20, 2014, the work sold for $44.4 million, including the buyer's premium. That price set an auction record for any artwork by a female artist at the time, not merely a record for O'Keeffe.

The title is sometimes shortened to Jimson Weed, but the full title identifies the flower and its sequence. It is also sometimes incorrectly described as a rose or lily; the subject is jimson weed, a plant in the nightshade family.
