You might be on to something there.  Perhaps the soaking & moist winter
stratification was the problem.  Parts of Russia & Mongolia are deserts.
Surely they get rain/snow but I don't know whether their wet season is in
spring, winter, summer, or fall.

If you have enough seeds, you should experiment with different techniques
rather than putting all your eggs in one basket, so to speak.

I know that some iris species take 2 to 5 years to germinate.  So maybe its
normal for yours to take a few years too.  Maybe you haven't done anything
wrong.  I'd definitely keep them around another year just in case.
