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