Actually, lately it's been colder. Yesterday I did several garden tours up there, one of the designers said it was 28 degrees when she got up Sunday morning and here it's almost June! She actually said it was more like 7b this past winter and she's been there 35 years. Of course, there are micro climates and a 'banana belt' so it all depends where you are. I figure, as long as I can grow citrus, and I've seen a few when touring properties, it can't be that bad.
