Seeds from pollen -free sunflowers?

I grow loads of sunflowers from seeds I saved seeds every year to use for mainly for cutting, but also for seeds and there's plenty of flowers left for bees, etc. and then seeds for birds. But some people don't like having the flowers indoors because of the amount of pollen that falls off.

I've seen 'pollen-free' sunflower seeds for sale and guess these are what commercial flower growers sow, but as they're so expensive I'd only want to invest in a packet if I could save seeds from them to grow enough for a few bunches of flowers every year.

But how can 'pollen-free' sunflowers produce seeds? Are the actually pollen-free, or pollen-retentive, reduced-pollen, etc.? If they produce seeds will they in turn produce plants with pollen-free flowers? I'm wondering about whether they'd get pollinated by nearby pollen producing sunflowers and lose the pollen-free characteristic. Perhaps the seeds are specially treated and would revert to pollen producing flowers anyway.

So has any one actually let any flowers from expensive 'pollen-free' varieties go to seed and then gone on to grow plants from those seeds?

I was thinking about bees because I only intended growing about 30 pollen-free ones, and I grow several hundred sunflowers every year.

 

As you said yourself, to produce seed they have to be pollinated anyway, so why bother?Talking about pollen has brought on my hayfever.
