Vincent van Gogh (Dutch, Post-Impressionism, March 30, 1853-1890): Three Sunflowers in a Vase, 1888. Created in Arles, France. Oil on canvas, 73 x 58 cm. Private Collection.

"'Why sunflowers?'—Sunflowers had a special significance for Van Gogh. He made 11 paintings of them.
Yellow, for him, was an emblem of happiness – in Dutch literature, the sunflower was a symbol of devotion and loyalty. In their various stages of decay, these flowers also remind us of the cycle of life and death." (nationalgallery.org.uk).
