Sunflower is an annual plant grown for its tall growth and large flowering heads. It develops a strong, upright stem with broad leaves and produces prominent blooms during the growing season. Sunflowers are well suited to warm climates and perform best in areas with full sunlight. They adapt easily to garden beds, borders, and open fields, growing well in well-drained soil with moderate fertility. This plant establishes quickly and produces flowers over a single growing season.
