Hi Laurie (great name, btw ;-)  ),

There is no trick, and the late bloom I sometimes enjoy on rebloomer 
transplants has nothing at all to do with anything I am or am not doing 
for them.  If I get a late stalk like that, it is because the rebloom 
stalk was already "set" in the original garden from which it was shipped 
to me.  If I receive reblooming irises from a warmer climate with 
significantly earlier spring bloom than I have here, there's a decent 
chance the rhizome will already be preparing for rebloom before it's dug 
out of its original garden.  When it arrives here and I plant it in my 
garden, it just continues the rebloom stalk development it already 
started in its original garden.  In my very short-season climate, it's 
quite common for new transplants that do manage to put up a late stalk in 
their first season to never do so again once they are fully acclimated 
(though the survivors will continue to bloom in the spring). 

Sadly, some new transplants that try to send up late stalks here get 
frozen out before the stalks can fully develop.  I lost half a dozen or 
so stalks to freezing weather this year, and it's unlikely those '02 
transplants will be able to develop new increases quickly enough to 
provide any bloom for me next spring.  Oh well.  You get a little, you 
give a little.
