I see it fairly often here, on ship-ins and my own seedlings.  Just today, I
went
through the ones planted last spring and noted the ones with, as I call it
'spent
primary' fans.  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.  I'd guess that ability is partly responsible for Renown
blooming so
early in spring.

A fair number of seedlings that have spent primary fans the spring after they
were
planted out go on to rebloom here.  I planted Walter Moores' Purple Reprise
late last
summer and the primary fan promptly died, (presumably from incipient stalk),
but three
nice increases came on right away.  Stalk coming on the biggest now.

Ironic when you have to wait to see rebloomers bloom.  Sorry I have no
practical help
to offer.

Mary Lou, near Indianapolis, Z5 - running about 2 weeks early.  Terrified this
will be a
repeat of the freeze disaster of 2007.
