Helianthus maximiliani is native to the Great Plains in central North America, and naturalized in the eastern and western parts of the continent. It is now found from British Columbia to Maine, south to the Carolinas, Chihuahua, and California.

 

The plant thrives in a number of ecosystems, particularly across the plains in central Canada and the United States. It is also cultivated as an ornamental

 

----------

  • The plant flowers in summer.
  • What is often called the "flower" of the sunflower is actually a "flower head" (pseudanthium), 7.5–12.5 centimetres (3–5 in) wide, of numerous small individual five-petaled flowers ("florets").
  • The outer flowers, which resemble petals, are called ray flowers.
  • Each "petal" consists of a ligule composed of fused petals of an asymmetrical ray flower. They are sexually sterile and may be yellow, red, orange, or other colors.
  • The spirally arranged flowers in the center of the head are called disk flowers. These mature into fruit (sunflower "seeds").
