Well,
It;s fascinating to hear about  all the different weather changes, 
particularly this season around the country.
Here in Seattle, we had an unusually warm autumn.  I was hiking in the 
Cascade Mountains in december without a jacket.  Then it came! Snow and 
temps in the 20's.
Needless to say, alot of marginally hardy material was not hardened off, and 
look like cooked spinach as I write this.
In this region, many gardeners live in 'Zonal Denial', raising things  that 
are reliably hardy in California, but in an odd winter, are rogued by the 
cold every so often.
One feather in our cap tho, is that this year the seed pans will have 
adequate cold for stratification, as species tulips, Hyacinthella, Crocus 
sp. etc have commenced germination.
Often, it take 2-3 seasons.
In bloom: grevillea victoriae, Viburnum bodnatense,Helleborus , Crocus, 
Daphne bholua,
Cyclamen coum cultivars,Narcissus rupicola,cantabricus,Galanthus sp et 
cultivars.
