Giant Sunflowers have massive 10 inch double blooms that are stuffed with tiny, densely-packed petals of richest golden-yellow, all the way to the center. What an unbelievably frilly flower on the 60 inch sturdy stems. Grow Giant Helianthus in a sunny location and in somewhat fertile well-drained soil. Keep the soil weed free and moderately moist while plants are young. Once established, Sunflower plants are somewhat drought and heat tolerant. They will flower mid-summer through fall.
Growing Giant Sunflowers From Seed: Sunflowers are the kings of the natural sunny summer garden, attracting butterflies and birds. Sunflowers are easy to grow from flower seeds.

Space the Sunflower seeds 12 inches apart, cover the seeds 1/2 inch deep, and thin the Sunflower seedlings to 24 inches apart.
