Carbonized seeds of domesticated sunflower (Helianthus annuus var. macrocarpus Ckll.) recovered from the Hayes site in middle Tennessee yielded an accelerator date of 4265 ± 60 B.P. This is the earliest date for domesticated sunflower, extending the known age of this eastern North American domesticate by 1,400 years.
An accelerator date of 1775 ± 100 B.P. obtained from a maize (Zea mays) kernel from the Icehouse Bottom site in eastern Tennessee is the most convincing early date for maize in eastern North America.
