Black Mammoth is an heirloom sunflower variety that is well-deserving of its name. Towering 8 to 10-foot-tall plants produce giant yellow flowers reaching up to 12 inches in diamet er. At maturity, the colossal heads are loaded with hundreds of glossy black seeds. We like to toss a few mature heads to our chickens and watch them circle around it frantically gobbling down seeds before the neighboring hen gets them. Fun for everyone. Blooms mid to late summer. Each packet contains a minimum of 50 seeds. Show more
