If you want to grow mega-tall sunflowers with mega-sized flower heads, American Giant Sunflower is the best choice. This fast-growing sunflower can grow 8-15 ft. tall and its flower heads are sometimes over 1 ft. across. American Giant has extremely sturdy stems so it's less like to topple during summer storms than other "giant' types. Its hybrid vigor means it'll grow fast and reach record heights in record time! This is a great choice if you're growing sunflowers for the tallest sunflowers or largest sunflowers contests at county fairs and festivals. It's also a fun choice for children to grow. 70 DAYS
