Sunflower (Helianthus annuus L.) belongs to the family Compositae Asteraceae and
 is an annual species with a spring-summer cycle and a typical big flower head. With a root apparatus that can extend deeply in the ground, the plant can access water supply often unusable by other cultivations. Highly resistant to low temperature, the sunflower is a fundamental and irreplaceable species in Central Italy (Tuscany, Umbria, Marche) where it often represents the unique possible cultivation in absence of water resources.

Sunflower has always been a typical plant of Central Italy lands. Its flowers and seeds are considered edible ingredients all around the world. Particularly, the seeds can be consumed as they are, or utilized for the oil production. Sunflower is actually cultivated to harvest its oleaginous seeds, used for oil extraction and for an excellent flour production.
