Mammoth Sunflower Seeds – Heirloom, Non-GMO, Non-Hybrid, Open-Pollinated

Grow towering Mammoth Sunflowers with our premium, heirloom, non-GMO, non-hybrid, and open-pollinated seeds!

Perfect for attracting pollinators, creating a beautiful garden backdrop, or harvesting delicious sunflower seeds for snacking or feeding birds.

Each packet contains 8g of seed, approximately 125 seeds.

Planting & Growing Instructions:

Days to Maturity: 75–90 days

Planting Depth: 1 inch

Plant Spacing: 18–24 inches apart in rows spaced 2–3 feet apart for best growth.

Days to Germination: 7–10 days with soil temperatures of 70–85°F.

Sun or Shade: Full sun is essential for optimal growth and large blooms.

For best results, sow seeds directly outdoors in well-drained soil after the last frost. Mammoth sunflowers thrive in warm weather and benefit from being planted in a sunny, wind-protected location. While starting seeds indoors is possible 2–3 weeks before the last frost, these vigorous growers prefer minimal transplanting. Once established, water regularly, especially during dry periods, to support their rapid growth and large flower development.

Ideal for gardeners of all skill levels, Mammoth Sunflowers add natural beauty, provide edible seeds, and help sustain local pollinators. Our high-quality seeds ensure reliability, making them a must-have for any garden project. Shop today and bring these iconic giants to your garden!
