About This

  • GROW GIANT MAMMOTH SUNFLOWERS UP TO 12 FEET TALL. These mammoth sunflower (Helianthus annuus) seeds are known for producing impressively tall plants with huge, golden-yellow blooms and dark centers. Reaching heights of up to 12 feet with flower heads as wide as 14 inches, they make a striking visual statement in any garden. Ideal for borders, backyards, or along fences, these sunflowers attract attention while offering natural beauty and pollinator support.
  • 520 PREMIUM HEIRLOOM SEEDS FOR HIGH-VOLUME PLANTING. This mega pack includes approximately 520 non-GMO, heirloom seeds, giving you the freedom to grow a large sunflower patch or multiple seasonal plantings. Whether you're cultivating for ornamental use, seed harvest, or wildlife feeding, the generous seed count ensures abundant growth. Each seed is open-pollinated and packaged for freshness, ideal for both home gardeners and large-scale hobby growers.
  • EASY TO GROW IN VARIOUS CLIMATES AND SOILS. Mammoth sunflowers are beginner-friendly and adaptable to a range of soil types and weather conditions. Simply plant in full sun and water regularly—no complicated maintenance required. Their hardy nature allows them to flourish in garden beds, field rows, or decorative planters. Perfect for school gardens, family projects, or anyone looking to enjoy a rewarding and low-effort growing experience.
  • ATTRACTS BEES, BIRDS, AND BENEFICIAL INSECTS. These vibrant sunflowers are more than just beautiful—they’re beneficial to your local ecosystem. Their large blooms naturally attract bees and butterflies, supporting pollination in your garden. After blooming, the mature seed heads provide a healthy food source for birds such as finches and chickadees. Enhance your garden’s biodiversity while enjoying stunning floral displays.
  • USA PACKAGED WITH PRIDE AND QUALITY TESTED. Grown, harvested, and packed in the USA, every seed is quality tested to ensure high germination rates. The packaging includes clear planting instructions, making it easy to achieve successful results whether sowing in spring or late summer. This seed pack is a reliable choice for gardeners who value American-grown products and consistent performance.
  • GROW A "LIVING FENCE" (PRIVACY SCREEN): Why build an expensive fence when you can grow one? Reaching soaring heights of 8 to 12 feet, these Giant Mammoth Sunflowers create a dense, beautiful natural barrier in just one season. Perfect for blocking unsightly views, creating shade, or adding privacy to your backyard.
  • HARVEST YOUR OWN ROASTING SEEDS: Not just a pretty flower—this is a food source! The "Mammoth" variety produces massive flower heads (up to 12 inches across) packed with plump, striped seeds. They are the #1 choice for roasting, snacking, or harvesting healthy, organic bird seed for your local wildlife.
  • BULK VALUE FOR SUMMER COMPETITIONS: With over 520 seeds per packet, you have enough to plant a whole field or start a neighborhood "Tallest Flower" contest. High germination rates make this the perfect fun, educational gardening project for kids and beginners to watch nature's magic unfold fast.
