This heirloom sunflower (Helianthus annuus) was originally introduced to the states in the 1880s, and is still the most popular sunflower around. Russian Mammoth towers over the garden with thick stocks that grow up to 12 feet, with flowering heads and yellow blossoms that can reach up to two feet in diameter and attract a great deal of attention from bees and other pollinators. As flowering heads mature they become loaded with large, delicious seeds. This crop can also be used for crop biomass generation - desiccated stalks add a great deal of carbon to any compost pile.
80 days from seed to flower. Annual.
