O’Keeffe was part of a movement of American artists changing previous norms

O'Keeffe's flowers are one of her most famous—and most misunderstood—motifs

Both critics and fans alike believed O'Keeffe's flower paintings were of female genitalia, though the artist never welcomed that interpretation. Part of the reason was that Freudian analysis was popular at the time they were first exhibited. Another was that her partner, Alfred Stieglitz, along with others in the art world, insisted on her work being erotic. Below is "Abstraction White Rose" from 1927.
