Mammoth Sunflower Seeds - Grey Stripe: Grow Towering Beauty & Nutritious Seeds

Experience the awe-inspiring beauty and bounty of Mammoth Sunflower Seeds - Grey Stripe, a stunning heirloom variety that delivers massive golden blooms and delicious, nutrient-packed seeds. These towering sunflowers are a garden showstopper, reaching heights of 6-12 feet with vibrant yellow flowers spanning 10-12 inches across.

Why Choose Our Grey Stripe Sunflower Seeds?

Our open-pollinated, non-GMO sunflower seeds produce thin-shelled, plump seeds with a distinctive grey stripe pattern. These high-oil content seeds are perfect for snacking, baking, or feeding wildlife. Each packet contains 50 seeds - enough to plant a 25-foot row of these magnificent plants.

Easy to Grow & Highly Productive

These hardy sunflowers thrive in poor soil and tolerate heat and drought, making them ideal for beginner and expert gardeners alike. Plant directly in your garden after the last frost, or start indoors 4 weeks earlier. You'll see sprouts in just 8-10 days, with first blooms appearing within 60-90 days.

Multiple Benefits Beyond Beauty

  • Edible delight: Enjoy raw or roasted seeds in breads, salads, or as snacks
  • Pollinator magnet: Attract bees and beneficial insects to your garden
  • Natural trellis: Support climbing plants like peas
  • Shade provider: Protect heat-sensitive plants with sunflower shade
  • Wildlife friendly: Birds love the seeds, chickens enjoy winter feed

Nutritional Powerhouse
