@Natalie. I think the sunflowers you grew from these hybrids may not produce any seeds at all. Unless there is some type of pollen from another sunflower variety that has any pollen capable of actually pollinating it. Nearly the whole point of offering Sunflowers like this, was mainly so as to not be bothered with having any seeds produced whatsoever!
Some people may not want to attract birds, squirrels, or especially any other rodents.
