Pansy

"The name 'pansy' is derived from the French word pensée meaning "thought", and was so named because the flower resembles a human face; in August it nods forward as if deep in thought. Because of this the pansy has long been a symbol of Freethought and has been used in the literature of the American Secular Union"
