Which Georgia O'Keeffe painting shows a monumental black iris from 1926?

Georgia O'Keeffe’s 1926 painting showing a monumental black iris is Black Iris.

Black Iris is an oil painting in which the flower fills most of the composition. O'Keeffe’s close-up flower paintings transform botanical subjects into expansive arrangements of curves, folds, and dark tonal passages.

The painting belongs to a period when flowers became one of her best-known subjects. She rejected the idea that such works should be read only as symbolic or sexual images, emphasizing instead the direct visual experience of looking closely at nature.

Several O'Keeffe iris paintings exist, including Black Iris III, so the titles can be confused. The 1926 work is generally known simply as Black Iris and is held by the Metropolitan Museum of Art in New York.
