Famous quotes containing the words perennial and/or sunflower:
“In old persons, when thus fully expressed, we often observe a fair, plump, perennial waxen complexion, which indicates that all the ferment of earlier days has subsided into serenity of thought and behavior.”
—Ralph Waldo Emerson (1803–1882)
“When van Gogh paints sunflowers, he reveals, or achieves, the vivid relation between himself, as man, and the sunflower, as sunflower, at that quick moment of time. His painting does not represent the sunflower itself. We shall never know what the sunflower itself is. And the camera will visualize the sunflower far more perfectly than van Gogh can.”
—D.H. (David Herbert)
