Helianthus annuus “Giant” is a striking sunflower variety known for its towering height—reaching up to 3–4 meters—and massive blooms with bright yellow petals and large dark centers. These fast-growing annuals are ideal for full-sun locations and thrive in well-drained soil. Often used as bold garden focal points or natural fences, Giant Sunflowers also attract pollinators and birds. Perfect for ornamental gardens, cut flowers, or even sunflower-growing competitions, this variety offers both visual impact and natural charm from seed to full bloom.
