Georgia O'Keeffe's 1926 flower painting featuring a large black iris is titled Black Iris.
Black Iris is an oil painting made in 1926 and is among O'Keeffe's best-known flower images. It enlarges a single iris so that the viewer sees its folds, curves, and dark central forms at close range rather than a small botanical specimen.
O'Keeffe repeatedly explained that enlarging flowers encouraged people to notice them. Her flower paintings are often discussed in relation to abstraction because their cropped forms emphasize shape, color, and texture as much as recognizable subject matter.
The work is frequently confused with Black Iris III, a related painting from the same year. Both belong to O'Keeffe's iris series, but Black Iris is the title of the specific work named in this question. The paintings are not simply interchangeable versions.
