American Giant Hybrid Sunflower 10 Seeds
The American Giant Hybrid takes the term "giant" in sunflower gardening to a whole new level. Most people set aside a part of their garden to go all out and cultivate a giant sunflower using every trick in the book for fertilizing and watering. The American Giant Hybrid was specifically created to make the most of your gardening skills. It's a massive (and we really mean massive) upgrade from the older garden varieties that you tended to, only to watch them topple over with the first strong wind after blooming. The American Giant Hybrid grows tall and remains upright long after the others have fallen. In fact, you might actually need to grab a saw to cut it down at the end of the season. Or you could just leave it standing through winter for the birds and squirrels to feast on the seeds, plus it’ll serve as a reminder to your neighbors of your gardening skills. Still skeptical about the American Giant being a giant sunflower? We've seen it reach heights of up to 17 feet! Now that's what you call a big sunflower.
