Sunflower is a plant native to Central America. From the 18th century began to be known and cultivated in Europe, mainly due to vegetable oil used as food, extracted from seeds, which in a short time became very popular. Also, the sunflower was and is used to extract from contaminated soil radioactive elements (uranium, cesium-137, Strontium-90) or other toxic elements like lead or arsenic.
