Sunflower

Sunflower (Helianthus annuus L.) is a seasonal plant of the popular kenikir-kenikiran (Asteraceae), both as an ornamental plant and oil-producing plant. This plant flower is very distinctive: large, usually bright yellow, with a large flower head (diameter can reach 30 cm). This flower is actually a compound interest, composed of hundreds to thousands of small flowers on one bump. Sunflower also has a typical behavior, the flowers are always facing / leaning toward the sun or heliotropisme. The French call it tournesol or "the traveler of the Sun". However, this trait is removed in new cultivars for oil production because it takes a lot of energy and reduces yield.

Sunflower is the national flower of Ukraine and the official flower of the state of Kansas, USA.
