A field of yet to be harvested sunflowers (Helianthus annuus) becomes a common sight across the farmlands of the Northern Hemisphere as the warm days of summer give way to the cool winds of autumn. Sunflowers are native to North America. Evidence indicates that the tribes of Central Mexico were growing wild sunflowers as early as 3000 BC. Some evidence even points to sunflowers having been domesticated by the native people of the Americas before corn.
