David's Garden Seeds Sunflower Mammoth Grey Stripe OS519 (Yellow) 50 Open Pollinated Seeds description and characteristics, review:
Tall Single. With huge flowers (often 10 or 12" inches across) these garden giants are developed for seed production (Sunflower oil, bird seed, etc.) 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. David's Garden Seeds is a Veteran owned business that has been offering quality products since 2009.
Blooms in 90 to 110 days
Seeds are Non-GMO and hand packed by David's Garden Seeds in the United States
