Linda, the post you made on growing iris in Hawaii for 2008 was based on his/her result with iris that had bud set when they arrived. Blooming in fall on iris arrived and planted that year. The report on the cultivar blooming repeatedly was also on a plant that had been planted previous year ( so I suspect). The lack of subsequent reports would suggest same results as Tom reported on iris moved to Florida. No bloom after second winter in that environment.
Plants evolve a complex of genetic sequences that rely on the environment and signals from the environment they exist in. When you remove these environmental signals,(or change them significantly) plants can no longer go through the complete sequence. Or go through it in strange way that is maladaptive, the more the change to environmental signals, the more maladaptive.

Shaub, I wasn't particularly promoting rebloomers, but that's what
others have suggested in the past as potentially having a better chance
of survival and bloom in zone 9/10.  I mentioned Byers' rebloomers in
particular because I think he was originally from TN?(zone 7 mostly, tho back then it may have been zone 6) and after he moved to zone 10? CA, he 
was crossing CA things onto eastern cold hardy/disease resistant things
like Immortality etc.

Immortality is a quirky beast.  I tried to get her to grow here several
times with no luck, but once she got established, she has thrived and
you can spot her from a good distance in most hot/humid gardens of
mostly once bloomers in mid-summer.  She's the one with the healthy
looking foliage. ;-)

But I'm not the only one who has had trouble getting her started.  And
she can be quite erratic about rebloom. Lloyd should have named her
Goldilocks, tho that would have been confusing. ;-)  Not too hot, not
too cold, not too wet, not too dry, not cultivated too much, not too
crowded in the clump, not too much fertilizer, etc etc
