What was the title of Georgia O'Keeffe's 1932 painting that became a record-setting American artwork?

Georgia O'Keeffe's 1932 record-setting painting was Jimson Weed/White Flower No. 1.

O'Keeffe painted Jimson Weed/White Flower No. 1 in 1932. It shows a large white jimson weed flower against a pale background, using the close-up scale and simplified forms associated with many of her flower paintings. The work was part of her sustained investigation of natural forms rather than a straightforward botanical illustration.

In 2014, the painting sold at Sotheby's for $44.4 million, including the buyer's premium. That sale made it the most expensive painting by a female artist sold at auction at the time. The record was later surpassed by other works, so the historical claim belongs specifically to the 2014 sale.

The title is sometimes shortened to Jimson Weed, but the full title identifies the work as White Flower No. 1. It should not be confused with O'Keeffe's separate flower paintings such as Black Iris III or Red Canna.
