Sunflower:

These flowers always turn towards the sun. They originated in Central and South America, and were grown for their usefulness, not their beauty. In 1532 Francisco Pizarro reported seeing the natives of the Inca Empire in Peru worshipping a giant sunflower. Incan priestesses wore large sunflower disks made of gold on their garments.
Sunflowers represented different meanings in many cultures. In China they symbolized longevity. In the Andes Mountains, golden images of sunflowers were found in temples. And North America Indians in the prairies placed bowls of sunflower seeds on the graves of their dead.
