Yes, obviously, the early bloomer freeze frequently, than the late. And 
the figures of Jeff Walters are convincing. But there is other point of 
view. Late blooming irises (gladiolus too) can grow and give seeds
successfully only in warm climate with long vegetative season. I think
there is connection between rate of growth and season of bloom.
Striking example - perfect very late LAST HURRAH. Grown over 6 year, was 
seen only onse - at cover of Schreiner's catalog. Therefore I treat late 
bloomer very warily when I choose irises for my garden. I think only fast
grown irises can be successfull in arctic region. Rebloomers are such, 
I agree with Lloyd. They can't to do second bloom, but first will be 
without fail.
However, I will be glad to know all the name of late bloomer which grow
well.
Thanks.
