What is the full title of Georgia O'Keeffe's famous 1932 flower painting Jimson Weed?

The full title is Jimson Weed/White Flower No. 1.

Georgia O'Keeffe painted the work in 1932, enlarging a white jimson weed blossom until it fills most of the composition. The slash in the title is part of the commonly used catalog title and distinguishes the painting from other flower works.

The painting is frequently shortened to Jimson Weed, which can create confusion with the plant itself or with O'Keeffe's other flower paintings. It was sold by Sotheby's in 2014 for $44,405,000, a record auction price for a work by a female artist at the time. Its title identifies both the plant and its place in a numbered white-flower sequence.
