Sunflower Giant (Helianthus Annuus) - This flower is a favorite of children to grow from Sunflower seeds. They are so tall and stately that both children and adults will be impressed. This Giant Sunflower variety has 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 72 - 84 inch sturdy stems. Grow Giant Sunflowers in a sunny location in somewhat fertile well-drained soil. Keep 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.
Sunflowers are the kings of the natural sunny summer garden, attracting butterflies and birds. Sunflowers are easy to grow from flower seed. After danger of frost has passed, directly sow Giant Sunflower seeds into prepared seed beds that are weed free and the soil has been loosened. Space the Sunflower seed 12 inches apart, cover the Sunflower seed 1/2 inch deep, and thin the seedlings to 24 inches apart.
