Overview

The Common Sunflower, Helianthus annuus, shines with large, vibrant yellow blooms reaching diameters of 6 to 12 inches. This annual towers at 6 to 10 feet tall, preferring full sun locations. Its sturdy stems and broad, coarse leaves create an attractive backdrop. Sunflowers provide excellent cut flowers and attract bees and birds. Space them 18 to 36 inches apart to accommodate their growth and ensure adequate sunlight.
