Talk about making a statement in the 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. All of the seed we carry at American Meadows is non-GMO, neonicotinoid-free and guaranteed to grow. Annual.

Product Recommendations

Description

With huge flowers (often 10 or 12" inches across) these garden giants are perfect for meadow planting. Remember, these are the ones that grow from 8 to a whopping 12 ft. tall, so unless you're planting them alone, scatter them throughout your meadow, or use them as a background screen. Kids love watching them grow so fast and so tall, and of course, they're magnets for songbirds. Enjoy!
