sunflower

This plant 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 "traveler of the Sun". However, this trait is removed in new cultivars for oil production because it consumes a lot of energy and reduces yield.
