An annual plant native to the Americas, the sunflower (Helianthus annuus) has been used since prehistoric times for ornamental and ceremonial uses, as well as for food. To date, the earliest domesticated sunflower seed was found at the San Andrés site in Tabasco, Mexico, dated to between 4,500-4,800 years ago. The second oldest domesticated sunflower seed discovered and dated to 4265 years ago, was found at the Hayes site in Tennessee.
I found this one and a small group of others, not that long ago, in my front yard. I didn't plant it. My guess is a few escapes from my bird feeder. Frostproof, Polk County, Florida.
