Grow a garden filled with the tall and mighty, Mammoth Gray Stripe Sunflower, from freshly harvested Helianthus annuus flower seeds. Mammoth Gray Stripe is an heirloom variety, which is sought after for its plump seeds. The plants themselves reach a towering height of roughly 6 to 10 feet tall, producing 10 to 20 inch wide flower heads. Each bloom will display bright yellow petals, which surround a golden brown center.


Categorized as an annual flowering plant, Mammoth Gray Stripe will grow quickly from freshly harvested seeds. The plants will produce a single stem, populated with dozens of spade shaped leaves. Each plant will produce hundreds of seeds by the end of the growing season, which can be baked and consumed or used as bird feed. You can also store some of the seeds away for regrowth next year as well.


Mammoth Gray Stripe Sunflowers are extremely tall, so they are best used as a backdrop plant, or sown in fields, by the masses. Primarily grown for their delicious plump seeds, Mammoth gray strip can also make a great addition to any sunflower garden as well. Plant them along fences or houses, and watch the insects cling to the massive flower heads.
