The sunflower (Helianthus annuus) is an up to 3 meters tall, annual plant in the composite family (Asteraceae). The sunflower can be sown from April to mid-June. The sunflower blooms from July to October. A plant can then produce several flower heads. The flower head can reach a diameter of up to 30 cm. Immature plants whose flower bud has not yet opened exhibit heliotropism: during the day, on sunny days, the flower bud turns with the sun. At night, the flower bud returns to the eastern position. This daily movement is brought about by uneven growth due to cell elongation of the flowering stem. This is because a sunflower has no pulvini (leaf pads). By the time the inflorescence opens, the inflorescence stem stiffens in the eastern position; heliotropism is then over. As a result, flowering sunflowers point east all day.
There is a cultivated form with a drooping head, which is attractive to farmers because the flowers are less damaged by birds and dirt from the air. source wikipedia.
