Interesting and exciting to see that your Iris unguicularis v. cretensis is
hardy in Zone 6, but am curious if you have actually had any Zone 6
temperatures in that time without snow cover?  -5F?  -10F?

Thanks to Bill Shear I learned that my Iris cretensis is hardy in zone 6.
I've been growing it outdoors ever since!  (About 7 years now.)  It has
bloomed on Christmas Day and New Years Day during favorable warm spells in
some years.  I love it!
