Georgia O'Keeffe is commonly associated with American modernism.
Her paintings enlarged flowers, bones, landscapes, and architectural forms until ordinary subjects became powerful compositions of color, shape, and line. This approach placed her within the development of American modernist art, especially as artists in the United States sought alternatives to academic realism.
O'Keeffe resisted being reduced to a single movement or interpretation. Critics often connected her flower paintings with symbolic or psychological meanings, while she emphasized the visual experience of looking closely at nature. Her work also moved between abstraction and recognizable subjects.
Pop art, Dada, and Minimalism are different movements with different histories. O'Keeffe's career began decades before Pop art and Minimalism became prominent, and her central classification is American modernism.
