What was the title of Georgia O'Keeffe's 1926 painting of a black iris?

Georgia O'Keeffe's 1926 painting of a black iris is titled Black Iris.

Black Iris is one of O'Keeffe's best-known flower paintings, in which an enlarged blossom fills much of the composition. Rather than presenting the flower at ordinary viewing scale, O'Keeffe made its forms appear monumental, encouraging viewers to study folds, curves, and tonal transitions.

The work belongs to the period when flowers became a prominent subject in O'Keeffe's New York-based art. Her flower paintings are often discussed in relation to abstraction, because recognizable petals are transformed into sweeping shapes and close-up structures.

The title is sometimes confused with the names of other iris paintings or with color descriptions supplied by viewers. The canonical title is Black Iris, and the work dates to 1926. O'Keeffe repeatedly rejected the idea that her flowers should be reduced to a single symbolic interpretation.
