Red Canna is a 1923 Georgia O'Keeffe painting showing a close-up of a red and yellow flower.
The work enlarges a canna blossom so that its curving petals fill nearly the entire composition. O'Keeffe's flower paintings are not botanical illustrations in the narrow scientific sense; they use magnification, simplified form, and color to make viewers look closely at familiar natural subjects.
Red Canna belongs to the period when O'Keeffe was gaining major recognition in New York. Alfred Stieglitz exhibited her work and helped introduce her paintings to audiences interested in American modernism.
The title can be confused with O'Keeffe's other flower paintings, including Red Canna, 1924 and Black Iris works. The 1923 painting is specifically known as Red Canna and is associated with her early large-scale flower imagery.
