Sunflower - Mammoth – 10 Seeds

Helianthus annuus

Mammoth is a type of sunflower that grows up to 3 meters high, producing large yellow flower heads up to 40cm across. It is a hungry plant and prefers fertile soil in full sun. The flowers bloom within 12-14 weeks, and the plant is useful for both producing edible seeds and attracting birds, bees, and butterflies to a garden. Mammoth sunflowers are fast-growing and a perfect variety for families with children.
