Common Sunflower (Helianthus annuus)
The tall, majestic sunflower, a member of the Aster (Asteracea) family, is found throughout North America. Commonly seen along roadsides, fields and other open areas it is the state flower of Kansas.
Blooming from late summer into fall the native Common Sunflower (Helianthus annuus) grows to six feet tall and produces yellow flowers two to five inches in diameter. The ovate leaves grow to a foot long. The stems, leaves and all parts of the Common Sunflower (except flowers) are roughly hairy.
  Prehistorically the Sunflower, cultivated by Native Americans for food and medicine is still grown and varieties of sunflowers, such as the Russian Giant, are cultivated for their oil rich and nutritious seeds. Sunflower oil, used for deep frying etc., may be purchased in many super markets and grocery stores. .
  The seeds produced by the Common Sunflower are an important source of food for wild birds and other wildlife.
  The flowers of the sunflower, facing the sun, seemingly “track” the sun. However, it is not the flower which turns, but the stem. The stem growing faster on the shaded side turns the flower in the direction of the sun.
