Sunflowers (Helianthus annuus) are significant annual herbaceous plants with diverse agricultural and environmental uses. Originating from North and South America, they were introduced to Europe in the 16th century. Their deep root systems allow them to absorb water and contaminants, including lead and radioactive materials, from soil and wastewater.

Economically, the plants are used for edible oil production and as a nutrient-rich food source. Sunflower seeds contain protein, fiber, vitamins E and B, and essential minerals such as magnesium, potassium, and iron. They also provide healthy unsaturated fats and phytosterols, which may support heart health. Experts note that while seeds are nutritious, they should be consumed in moderation, particularly avoiding varieties with excessive salt. Major global producers include Russia, China, India, the United States, and Turkey.
