MAMMOTH SUNFLOWER SEEDS, GIANT GREY STRIPE: 300 heirloom, non-GMO Helianthus annuus seeds per pack. Plants grow 6–8 ft. tall with one large golden head per stalk, striped seeds, and broad pollinator and bird value across USDA zones 2–11. GIANT SINGLE HEAD WITH GOLDEN BLOOMS: Each stalk produces one broad flower head, 8–10 in. (20–25 cm.) across, with golden yellow petals surrounding a dark brown centre disc that fills with large grey-striped seeds by late summer or fall. TOWERING HEIGHT FOR BORDERS AND BACKDROPS: Giant Grey Stripe Sunflowers grow 6–8 ft. (1.8–2.4 m.) tall on single stalks, suited to back-of-border plantings, tall privacy screens, and garden backdrops in full sun locations. FAST GERMINATION IN 7 TO 14 DAYS: Giant sunflower seeds for planting germinate in 7–14 days at 70–75°F (21–24°C). Direct sow ½–1 in. deep after the last frost in average, well-drained soil. No indoor starting is needed. EDIBLE SEEDS FOR SNACKING AND HARVESTING: The large grey-striped seeds are edible once ripe. Roast and salt them as a snack, or leave the drying heads standing so songbirds can feed directly in fall. Blooms 90–110 days from sowing. POLLINATOR AND WILDLIFE FRIENDLY PLANTING: Pollen-rich heads support bees and butterflies through summer. As heads ripen, the seeds draw songbirds, making this a suitable choice for wildlife gardens, bird gardens, and pollinator plantings. ANNUAL SUNFLOWER, BLOOMS FIRST SEASON: Grown as an annual across all USDA zones 2–11, Giant Grey Stripe Sunflowers bloom the same summer they are sown. Sow after the last spring frost through early summer for summer-to-fall flowering. DIRECT SOW OUTDOORS FOR BEST RESULTS: Sow mammoth sunflower seeds for planting directly in the garden after the last frost. Space plants 18–24 in. (45–60 cm.) apart so each stalk has room to develop fully. Stake in exposed or windy sites. HEIRLOOM, NON-GMO, OPEN-POLLINATED SEEDS: Every seed in this pack is heirloom quality, non-GMO, and open-pollinated, preserving the Giant Grey Stripe genetics. Save seed from your best heads to replant in future seasons. VERSATILE LARGE SUNFLOWER SEEDS FOR GARDEN USE: Suited to edible seed harvests, bird and wildlife gardens, tall borders, cottage gardens, and cut flower use while young. Also suited to large sunflower seeds for planting outdoors.
