Georgia O'Keeffe's 1926 painting of an enlarged dark iris is titled Black Iris.
The painting presents a close-up view of an iris, enlarging the flower so that its petals fill much of the composition. O'Keeffe often used this approach to make familiar natural forms appear unfamiliar and monumental.
Black Iris belongs to the group of flower paintings that established her reputation in New York during the 1920s. Critics and viewers sometimes interpreted these works through a Freudian lens, especially as symbols of sexuality. O'Keeffe rejected that interpretation and insisted that viewers should look at the flowers themselves.
The painting is held by the Metropolitan Museum of Art in New York. It is distinct from her later series of red, white, and other colored flowers, despite the recurring close-up format.
