More than 65 species are native to Central and North America, while three species are native to South America.

They make perfect graduation flowers and celebrate personal and professional accomplishments. Sunflowers are considered highly auspicious, and the color yellow is often associated with intelligence and vitality.

Sunflower’s name comes from the Greek for “sun,” or helios, and “flower,” or anthos.

11) Sunflowers figure in the Greek legend of Clytie and Apollo 

Clytie was jealous of Apollo’s new love interest, Leucothoe, so she tattled to Apollo’s father, who buried Leucothoe. Apollo turned her into a sunflower so she could watch his chariot move across the sky every day.

His 12 sunflower paintings are among his most famous works. He created the paintings in France between 1887 and 1889 and referred to sunflowers rather possessively as his own artistic signature. Van Gogh’s love of sunflowers inspired his artist friend Paul Gauguin to paint “The Painter of Sunflowers,” an image of van Gogh creating, you guessed it, his sunflower paintings.

13) Van Gogh and Gauguin aren’t the only painters to feature sunflowers.
