?
Paul, this is a very interesting observation.? Please continue to share.? I've not tried artificial methods but I do like to read the results of other and learn from the processes.?

When we share, we all benefit.? In addition, the plant culture we all love benfits too.?

I will note that six weeks of cold is not the norm for bearded Iris seed to 
complete a "normal" cycle.  Yes, some crosses do produce seeds that germinate 
that early.  I had one this past winter do that and observed the same thing with 
the seedlings being weak.  They actually seemed disease prone with a wierd 
malady I had never seen or yet explained.  It ALMOST looked like scorch, but it 
only affected the early geminants.  The other seedlings that germinated arter 12 
weeks were fine.

The remaining ones that hadn't germinated could be the genetic result of a 
normal twelve week (or further extended) gemination cycle.

We had discussed in ealier emails that later germinants might be stronger or may 
even be better rebloomers than those that germinate early.  Time will tell as I 
observe my surviving seedlings and proposed crosses further.

that it was time for warmer temperatures I have not seen a signifigant number of 
new pods germinate.  In addition the flush of new germinants seems to stop 
altogether after about a week.  That could just be the ones that were past "the 
point of no return."  Among those that germinate in warm or alternating stages, 
it seems they have a harder time making it to Pop-Tart stage.
