Researchers have found evidence that the sunflower, Helianthus annuus, has a long history of domestication and cultivation in Mexico, occurring well before the Spanish Conquest in the early 1500s. Evidence points to the sunflower having been cultivated as far back as 2600 B.C. This is an artist's interpretation of how the lore of the cultivated flower could have been included on long-lost Aztec artifacts.
