Looking for a truly colossal sunflower? Look no further than Black Mammoth! The heads on these giants grow up to 12 inches in diameter and are loaded with black sunflower seeds. The stalks can reach heights of 10 feet or more, making them the perfect addition to any garden or landscape.
GROWING TIPS
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.
