Now that I've more or less met my primary breeding goal of getting a crate load of seedlings in a range (ok, so it's still a fairly small range..) of colors that will bloom here more or less regardless of the weather, I was trying to work on mixing in some of the warm season "summer" rebloomers.
I really wanted to find out whether or not they could mix with my tough kids from "summer" bloom background (but don't rebloom here) to produce a few summer blooming seedlings. So I could figure out what to do next.
I didn't expect to lose nearly <all> the spring bloom from them, but that's just 'cause I got all swept up in the idea & forgot that's what can often/usually happen here.
Of the 22 I bought last fall, 9 definitely have dead/rotting terminals, 5 more look like they are failing, just taking longer to rot off. I haven't found all the pots yet, so am not positive about the rest.
The wonderful news is that some of these have put up healthy stalks on increases that formed after September. More fuel for the idea that the trait of putting up extra stalks on winter increase is linked to rebloom.
So many of these warm climate (summer dry) selections don't survive to bloom more than one spring here, I was pinning my hopes on at least getting one round of pollen. Oh well...plenty of other rabbits available to chase this season. 

 <Since Valentine's Day and Avona are both warm weather
rebloomers,
stands to reason they had stalks starting down in the rhizome that were too
far
along to put 'on hold' until spring. I think some iris are better at putting
stalks on
hold than others. >
