Howdy Linda,
     What do you regard as an early freeze?  i.e What temperature did you 
get down to?  We get down to -8'c (ish) and both varieties are fine, but I 
realise that this is nothing compared to some parts of the world.  I. 
unguicularis has been growing here for years and we've been down to -11'c in 
the past without hurting it.  If your plants are in pots they will be more 
likely to be frost affected as their roots get colder..... my I. lazica is 
now in the ground which is what it seemed to need to flower.

  It didn't bloom last winter/spring & I'm not

Does this mean that I. lazica is only a late Winter/Spring flowerer?  Our I. 
unguicularis have been flowering since April (Autumn) but the I. lazica has 
only just sent up its first flowers.  Do you mean that it may flower later 
than the rest?  In the past I've found that I can expect flowers on I. 
unguicularis from around March (sporadic) to September (sporadic) with 
pretty solid flowering in between.  It's currently the end of August and we 
are having the best flowering from them for the year (Cold snap for the last 
month after a mild Autumn.... this may have brought I. lazica into flower).  
It'll be interesting if I. lazica brings the flowering time for the winter 
irises through into the TB time.  That'd be cool!!

Cheers.        Paul T.
