American Giant F1 pushes the label of “giant” to new frontiers in sunflower gardening. The American Giant is a quite large sunflower, really it is huge sunflower. Almost everybody saves a corner of the garden to pull out all the stops and grow a giant sunflower specimen using all their fertilizer and watering tricks. American Giant Hybrid was developed especially to respond to your best gardening efforts. It is a huge (and we mean, huge) improvement on the old garden varieties that you nursed along in the garden only to see them fall to the ground with the first big wind after flowering. American Giant Hybrid grows tall and stays standing long after the others fall. In fact, you may have to literally get out a saw and cut it down at the end of the year. Or leave it through the winter for the birds and squirrels to enjoy the seeds and to remind your neighbors of your gardening prowess. Don’t believe that the American Giant is a huge sunflower? We have seen it grow as tall as 17 feet! Now, that is a large sunflower.
