Sorry about that...it's been a while since I posted a picture...let me see if this works. If not...I'll go back to square one realizing that the memory cells need a bit of refreshing.

Here is a link that might be useful:

I don't know about overwintering your passie up where you are, but I'm almost positive its a p. caerulea, just as you thought.
Hopefully, somebody else can answer your other question.

That's definitely caerulea.

You might have luck overwintering her... West side near the chimney you say? Hopefully there's an actual fire in that chimney most of the winter rather than "Oh it's got a fireplace" as that will keep the ground from freezing completely solid & you might have a chance.

I spent several years up by Watertown & brought everything in... As that experience brought a whole new meaning to the term "arctic".

If the top hasn't died already I would take a few cuttings & try to root them- Keep those guys inside & if the big one dies then at least you still have something.

I agree with krstofer. It may make it in the location you have, but always take cuttings to be on the safe side.

Great pic!! I don't think you should have any problem with it... some heavy mulch and positive drainage.. BUT I always take cuttings even if it has come back for yrs.. The are very easy to root and if yours makes it will ahve some to share or plant somewhere else in your yard...
