Mammoth Grey Stripe Sunflower

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. Reaching 8–12 feet under good conditions, they create serious visual appeal while also serving a purpose in pollinator and wildlife plantings.

Bright yellow blooms draw in bees, butterflies, and other beneficial pollinators throughout the growing season. As plants mature, the large seed heads provide a natural food source for deer, doves, pheasants, songbirds, and other wildlife. Easy to grow and quick to establish, these sunflowers perform well across a wide range of soil types when planted in full sunlight.
