Surely, once you've grown your first batch of sunflowers, you need never buy
the seeds again....

The commercial varieties of Sunflower are grown for their seed and oil
properties. Those you have purchased are most likely garden varieties
supposedly much more attractive than those grown in fields. They might
even
be dwarf or nearly double.
Those from the birdseed will be of the field variety.
Best Wishes.
