Sunflower is a flower plant belonging to the Asteraceae family, and its scientific name is Helianthus annuus. Its name comes from the fact that as it grows, it turns its flowers to follow the position of the sun, chasing the sun as if it were one side of the flower facing the sun.

The flower language of sunflower is "revere the sun and love life". Its flower disk has large amounts of pollen and tiny flower spokes in the center and is an important food source for many insects and birds. Sunflowers can be used as ornamental plants and are often used to make edible oil. The seeds contain high-protein oil, which is beneficial to human health.
