Georgia O'Keeffe's 1926 painting featuring a dark iris is titled Black Iris.
The painting is an enlarged close view of an iris, a subject O'Keeffe transformed into a monumental abstracted flower form. Rather than presenting the entire plant in a conventional botanical arrangement, she focuses attention on the layered petals and the deep central folds.
Black Iris belongs to the series of flower paintings that made O'Keeffe widely recognized in the 1920s. Her enlarged flowers were often interpreted through the lens of Freudian symbolism, but she rejected the idea that viewers needed to impose a sexual meaning on them. She repeatedly emphasized looking closely at ordinary objects.
The title is sometimes confused with other O'Keeffe flower works, including Dark Iris No. 2 and her many paintings of white flowers. The exact title Black Iris identifies the 1926 work in question.
