Stripe gray and white seeds.  Mammoth Sunflower is an easy to grow summer annual.  These seeds produce stately yellow sunflowers with enormous heads, more than 1' across approximately, which provide spectacular beauty first, then seeds for roasting or birdfeed.

Instructions: After all danger of frost, sow Organic Mammoth Sunflowers seeds in open ground well exposed. Cover with 1" of soil. When plants are 4", thin.

Suggestions: Excellent for tall blooming backgrounds and screens for unsightly places. Harvest seeds by cutting flower heads when back of flower head turns yellow, then hang downward in a warm, dry place. I did have good success with these sunflowers and they were very tall and sturdy.
