Georgia O'Keeffe's 1926 painting featuring a black flower form is titled Black Iris.
The oil painting presents an enlarged iris in dark tones, with the flower's central structure filling much of the composition. O'Keeffe often magnified flowers so viewers encountered them at an unexpectedly intimate scale, turning a familiar natural subject into an abstract-looking design.
Black Iris is frequently discussed alongside her other flower paintings from the 1920s. Critics and popular commentators have sometimes interpreted her flower imagery symbolically, particularly in sexual terms, but O'Keeffe rejected the idea that her paintings should be reduced to such readings.
The title is often extended in catalogues to Black Iris III for a particular version in the series. That distinction matters: O'Keeffe made multiple iris-related works, so the shorter title should not be treated as a complete catalogue identification in every context.
