A few years ago we had a late Winter storm and we lost a lot of our Azaleas. They should, actually, stand through the Winter and come back well in the Spring. The problem back a few years was that they had started to bloom when the cold snap hit in April. This year they have bloomed for late Fall (they bloom Spring, Summer and Fall...called an Encore Azalea they are beautiful and display their beauty three times a year) and I think that despite the snow covering they recieve they'll bloom as expected in Spring...at least I hope so!
