The earliest known examples of fully planted sunflower have been found in Tennessee and dated to around 2300 BC. Many native Americans used sunflower as the symbol of their Sun God, including the people of Aztecs and the Otomi of Mexico and the Incas in South America.

Sunflowers "whole seed" (fruit) are sold as snack, after being roasted in ovens, with or without salt added. Sunflowers can be processed into a peanut butter alternative, sun butter. In Germany, sunflower is mixed together with wheat fluor to make Sonnenblumenkernbrot (literally: sunflower whole seed bread), which is quite popular in German-speaking Europe.
