Native to North America, it is cultivated worldwide for its large, bright yellow flower heads and nutrient-rich seeds, which are consumed as food, pressed for oil, or used as bird feed. Traditionally, various parts of the plant—including seeds, oil, and petals—have been used in folk medicine for their antioxidant, anti-inflammatory, and cardiovascular-supporting properties. With its ornamental, culinary, and medicinal significance, Helianthus annuus remains a widely valued species in agriculture, gardens, and traditional practices globally.
