Sunflowers thrive in all 50 states in the U.S., most blooming during the summer months. Their native range also extends through Canada, Northern Mexico and Central America. The sunflower's native environment is dry, wide open spaces such as prairielands, plains and meadows.

Where do Sunflowers grow best?

Sunflowers grow best in locations with full sun. They are remarkably tough and will grow in any kind of soil as long as it is not waterlogged. They do fine in soils that are slightly acidic to somewhat alkaline (pH 6.0 to 7.5).

Where do sunflowers grow in the garden?

Choose a sunny spot near the back of your garden so the sunflowers receive at least six hours of sunlight each day, yet won't shade other plants. Planting them in a narrow, rectangular border to edge the garden is ideal, either against an existing fence or to form a living fence.
