Which flower appears in Georgia O'Keeffe's famous painting Red Canna?

A canna lily appears in Georgia O'Keeffe's famous painting Red Canna.

O'Keeffe painted numerous enlarged views of flowers, including several works based on cannas. Her Red Canna paintings use intense red, orange, and crimson forms that fill the picture surface, encouraging viewers to look closely at the flower's folds and color transitions. The series is associated with her interest in making small natural forms seem monumental.

O'Keeffe often said that people overlooked flowers because they moved quickly past them. By enlarging them, she gave viewers time to see their details. The flower in Red Canna is not an iris, although irises are also important in her work, and it is not the white jimson weed associated with her 1932 auction-record painting. Botanical identifications can vary by cultivar, but the work's title and subject are conventionally linked to the canna lily.
