Mine didn't but the soil is not warm enough yet to expect anything.

Anner whitehead raised the point that some iris seeds need light
for germination in a previous discussion about germination in the
Iris-L. This is true for I virginica var shrevei at least. I didn't
know about this when I sewed both your seeds and the ones from
SIGNA and I couldn't retrieve them from the soil inthe pots.  Will
try again next year (If you would like to help with this.  TIA). 
Next year I will try with the seeds on the soil surface, freezing
and recycling (in and out of the fridge for 12 hours every day) for
2 months and then sit in front of the window until something
