Which artist was known for painting flowers and landscapes during the Great Depression?

Georgia O'Keeffe is renowned for her distinctive paintings of flowers and landscapes, particularly during the Great Depression era. Her artwork captures the essence and beauty of nature with a unique and modern approach that emphasizes form and color. O'Keeffe's work during this period was significant not only for its aesthetic appeal but also for its role in expressing the emotional landscape of America during challenging times.

While other artists listed also have strong connections to specific themes in their work, they do not align with the focus on flowers and landscapes specifically during the Great Depression. Vincent van Gogh, for instance, was active in the late 19th century and is famous for his expressive use of color and brushwork but not during the Great Depression. Pablo Picasso is celebrated for his contributions to Cubism and other styles, while Frida Kahlo is identified for her deeply personal and symbolic self-portraits. Thus, O'Keeffe stands out as the artist most associated with the floral and landscape themes in this historical context.
