Make a statement in your garden! Mammoth Grey Stripe has huge blooms, growing up to 12" + across. Each bloom sits atop stems that grow to be 8-12 ft tall. Extremely fun to watch grow, Mammoth Grey Stripe is a great choice for scattering throughout the meadow, using as a background or privacy screen, or creating a child's first garden. Massive seed heads are good for harvesting and roasting or leaving in place to feed birds. An heirloom, open-pollinated Sunflower, Mammoth Grey Stripe is loved by a variety of bees, butterflies, and hummingbirds, too.
