Georgia O'Keeffe's 1927 work Red Canna depicts a canna lily.
O'Keeffe made a series of paintings based on canna flowers, including Red Canna. She enlarged the blossoms until their folds and curves filled the picture surface, turning a botanical subject into an abstract-looking composition of intense red, orange, and darker tones.
The canna series is important because it shows how O'Keeffe used close-up scale to transform familiar natural forms. Her flower paintings are often described as abstractions, but she generally began with a real flower and simplified or magnified its visible structure rather than abandoning recognizable subject matter altogether.
Red Canna is therefore different from her works titled Black Iris and Jimson Weed/White Flower No. 1. Those paintings also use enlarged flowers, but they represent different species and belong to different series.
