Mammoth Grey Striped is a towering heirloom sunflower grown for its massive heads and heavy seed yield. With thick stalks that stretch up to 12 feet tall and blooms reaching a foot across, it makes a bold statement in the garden while drawing in pollinators by the dozen. The large, striped seeds are excellent for roasting or feeding the birds once dried. First introduced in the late 1800s, this variety has remained a favorite for generations thanks to its reliability, beauty, and sheer size. Ideal for back borders, windbreaks, or adding a bit of spectacle to the summer garden.

How to Grow

Plant seeds directly in the garden after average last frost date when soil has warmed up. Optimum soil temperature for seed germination is 60-75°f. Succession plantings can be made every 1-2 weeks for continued harvest. Or, start seed indoors 3-5 weeks before transplanting into the garden. Transplant to the garden 1-2 weeks after your average last frost date. Sunflower is sensitive to transplant shock so carefully set in the garden.
