Sunflower
Helianthus annuus
Sunflowers thrive in full sun and well-draining soil, requiring at least 6-8 hours of direct sunlight daily. Water regularly at the base to keep soil evenly moist, avoiding overhead watering that can promote disease. They are fast-growing and low-maintenance, making them an excellent choice for beginner gardeners and pollinator-friendly landscapes.
