American Giant is a super tall hybrid sunflower is a sure bet to sell to homeowners who are itching to grow the tallest sunflower in the neighborhood! Growing anywhere from 8 to 15' tall, American Giant Sunflower is less likely to fall over in wind or rain compared to other "giant" types. It also makes an excellent windbreak along hedgerows or the perimeter of properties. Best yet, leave the heads on for seed for the birds later in the season!

"They are good and 10ft tall!"
Planted Giants in zone 10A
"The Giant seeds from Harris sprouted at nearly 100%. I planted at least 140 seeds in my back yard. I planted at the beginning of April and had flowers by the end of June. After removing the first bloom I continued to get smaller blooms on the stem. They bloomed about 1 week earlier than the Mammoth seeds I purchased. I will replant again this summer in August. I would also purchase these again."

I’m satisfied
"I haven’t grown Sunflower for several years because of a rabbit infestation. Out of the twelve seed I planted in my fenced garden I had nine survive the insects and other predators. They produced beautiful multipleheaded flowers. Unfortunately, a heavy rain storm made the flowers look bedraggled so I didn’t send a photo."
