Helianthus annuus

Our tallest sunflower, this heirloom variety was first offered in the 1880s and is still prized for its gigantic flowers and abundant, nutritious seed. As they mature, the heavily laden seed heads bend forward like a giant outdoor shower. Allow to dry on the stalk to harvest seeds.
