I had the same experience, but only with about 3 seeds leftover from
spring.. From what I've read in the generic seed germination reviews,
this isn't surprising. Some of the inhibitors apparently just need time
to go away (different compounds break down, are used up, leach out, or
are converted to something else) or the "enhancers" (I forget what they
called them) need time to develop. There are a lot of different
chemicals in different concentrations and in different parts of the
seeds, & all of these things react at different rates and go in
different directions depending on temperature, moisture and patterns of
both. Wouldn't surprise me a bit if all these things vary among the
ancestral iris species (not to mention mutations) & who knows what mix
an individual seed will have.

have the fall sprouting after a
thorough cooking and drying out period in the
summer ahead of the fall.>
