Wild H. annuus plants typically had, many small branching stems, with multiple small heads
Over time, humans selected for larger seeds and a single large flower head.

Sunflowers are in the daisy family, or asteraceae

Archaeological evidence, including larger sunflower seeds and depictions. Shows that H. annuus was domesticated by indigenous peoples around 2.8 to 2.3 thousand years BCE
In what is now the Mississippi Valley; Tennessee, and, Kentucky in the eastern united states

Seeds and remains also appear in Tabasco, Mexico, suggesting sunflower was cultivated in parts of Mesoamerica by 2.6 thousand BCE
Possibly transported by local groups, or through contact with eastern North Americans.

Sunflowers grow from seed
Wild populations naturally produce seeds that sprout new plants the next season.

Indigenous farmers selected plants with larger seeds, bigger heads, and fewer branches
Over generations these selections led to better production and management for food use.

Sunflower seeds were a staple food before and after domestication

They were eaten raw, roasted, ground into flour, or pressed for oil
Seeds and plant parts were also used for dyes, medicines, animal feed, and fibre.

Some groups connected sunflowers with solar deities and cosmology
The Zuni used blossoms in ceremonial contexts.

Wild sunflowers likely spread across their native range through birds and small animals eating and dropping seeds; this is typical for many seed-bearing plants.

Did you know? The tallest sunflower on record achieved 10.9 m (35 ft 9 in). (1)

Particularly the great plains region of what is now the United States & Canada. The sunflower, or helianthus annuus, is native to north, (& parts of central) America. Check it out today.
