EXCLUSIVE – These grand giants are fun and easy to grow with dramatic results. Kids of all ages will love them! The big-framed, strong plants reach from 12 to 16 feet tall to follow the sun; their brilliant golden flower faces make the entire garden a glorious bright summer celebration. A row of Sunzilla makes a wonderful living hedge that grows before your eyes. After flower petals drop and seeds have matured, the big heads of plump kernels make a feast for neighborhood songbirds.
