About Our Seeds

All Seed Needs products are non-GMO and untreated. Our seeds are stored in a temperature-controlled, moisture-free facility and are always packaged for the current and following growing seasons. You can count on 99% pure seed, with no added fillers.

Our heirloom varieties have been purposefully bred, selected, and passed down through generations, ensuring they will breed true to the parent seed. Flowers from our seeds will attract a host of beneficial insects, such as butterflies, bees, and ladybugs.

Mammoth Gray Stripe Sunflowers

Grow a garden filled with the towering Mammoth Gray Stripe Sunflower, an heirloom variety prized for its plump seeds. These annual plants can reach 6-10 feet tall, with flower heads up to 20 inches wide, featuring bright yellow petals surrounding a golden-brown center.

Sowing and Growing

Sunflowers prefer not to be transplanted, but can be started indoors 6-8 weeks before the last frost and transplanted with the entire peat pot. Direct sow outdoors when the weather is warm and all danger of frost has passed.

Sunflowers require full sun and moist, well-draining soil. They grow long taproots, so be sure to address any compaction before sowing. Germination occurs within 7-10 days, and mature plants can be spaced 16-20 inches apart.

About Seed Needs

Seed Needs was founded by a 15-year-old with the goal of bringing his family closer, retiring his father, employing friends, and most importantly, helping people. We're proud to offer a wide range of open-pollinated, heirloom flowers, herbs, and vegetables, as well as continually donate to St. Jude Children's Hospital and the ASPCA.
