@ShawnSteve, you never actually explained how companies produce mass amounts of pollen less varieties? If they cannot be propagated by roots or cuttings then every pollenless flower pollinated by a fertile variety would result a hybrid which would not be anything like the labeled parent variety. So how do they manage to keep these varieties in production year after year?
I did manage to plant pollenless sunflowers and fertilize them by planting a variety with pollen of the same color, but I could not replicate the original cultivar. I do not know how it's possible.
