Mammoth Grey Stripe Sunflowers are one of the most popular giant sunflower varieties, known for producing tall plants and massive seed heads filled with large striped seeds. Under good growing conditions these sunflowers can reach heights of 8–12 feet, making them a standout addition to gardens, pollinator plantings, and wildlife habitats. These sunflowers produce bright yellow blooms that attract honey bees, butterflies, and other beneficial pollinators throughout the growing season. As the plants mature, the large seed heads become a natural food source for songbirds, doves, and other wildlife. Mammoth Grey Stripe Sunflowers are easy to grow and establish quickly in most soil types when planted in full sunlight. They are a versatile planting option for backyard gardens, homesteads, pollinator strips, bird habitats, or larger sunflower patches. Plant in spring once soil temperatures have warmed. Sow seeds ½–1 inch deep with good seed-to-soil contact. Space plants 12–24 inches apart, or broadcast at approximately 15–20 lbs per acre for larger plantings. Whether you’re looking to grow towering sunflowers in your garden or support pollinators and wildlife, Mammoth Grey Stripe Sunflowers are a reliable and rewarding planting.
