While sunflowers are thought to have originated in Mexico and Peru, they are one of the first plants to ever be cultivated in the United States. They have been used for more than 5,000 years by the Native Americans, who not only used the seeds as a food and an oil source, but also used the flowers, roots and stems for varied purposes including as a dye pigment. The Spanish explorers brought sunflowers back to Europe, and after being first grown in Spain, they were subsequently introduced to other neighboring countries.
Today, the leading commercial producers of sunflower seeds include the USA, Russian Federation, China ,Peru , Argentina, Balkan countries
