Do you know Misconception about Sunflower (Helianthus annuus, Family: Asteraceae)

There is a misconception about the sunflowers. It is said that the sunflowers turn continuously during the day to face the sun. It is absolutely wrong; sunflowers do not change the direction any time of the day. When large fields of sunflowers are grown, the variety is chosen is for its seeds, which have high oil content. This oil is, as we know all, is used in cooking. Such varieties of sunflower plants normally have a large, single, flower growing on apex. Normally all the flowers in such field cultivation face any one direction (but do not change their direction as sun shifts). However, if there are two or more flowers growing on the apex, each faces a different direction. Smaller, decorative sunflower varieties have flowers facing all directions. Even large flowering varieties, if grown in pots and kept in different locations, flowers growing on them grow in any direction.
