@Serjio, I found this article that may help you.

I copied this paragraph since it explains about pollen storing:
"I've assembled a modest collection of paraphenalia for hybridizing. I use gelatin capsules for storing pollen (size 0 for small anthers and 00 for larger ones). The capsules are kept in a peanut butter jar with packets of desiccant to keep the pollen dry. I will also be trying glassine envelopes for pollen, as it seems these may be less airtight and help in keeping the pollen dry. (Update: I now use the envelopes exclusively.) The jar is kept in the fridge during bloom season, and then transferred to the freezer to store pollen of late bloomers for use the following spring. Pollen should be dry before closing the capsules."
Pollen also can be shared and exchanged. So you don't have to grow every single iris to get crosses that you desire.
If one starts just barely gleaning possibilities the numbers involved are near infinite!
