Care
Sunflowers thrive with plenty of sunshine and regular watering to keep soil evenly moist (but not waterlogged). Taller plants like Giant Single may benefit from light staking in exposed sites to support the heavy blooms. Regular watering during dry spells will maintain strong growth and vibrant blooms.
