Here I am offering seeds from Helianthus giganteus, also known as the Giant Sunflower, and Tall Sunflower. This tall perennial likes to live in full exposure to the sun, and it produces edible seeds and roots. Growing to a height of about 8 feet tall this flower easily attracts a wide variety of bees, birds, and butterflies. USDA Hardiness Zones 5 to 11
