Jeff, My I mssouriensis seeds from Marte have not germinated yet. They
spent the winter outside like yours but we are in a frost pocket and
they will probably take longer.

I got some PCN seeds from Vicky Craig and was able to take advantage of
Rodney Barton's advice and do the initial incubation at 50-5oF which
allowed nearly all the seeds I had to germinate. A friend of mine who
had thesame seeds but not the same window couldn't get hers to
germinate. So the preincubation at 50oF is important. 

I got some I versicolor seeds from SIGNA and haven't been able to get
these to germinate at all. I've just put them in the freezer for a week
and will take them out tomorrow and see what happens. Am planning to
alternate 24 hours in the fridge with 24 hours out of the fridge which I
found helped with the I typhifolia germination.
