Also there's a huge Canary & Sylvestri basically across the street. You can see the similarities.

Phoenix hybridise very easily. In fact it can be difficult to get a pure specimen of one species. That one certainly has the characteristics of CIDP and sylvestris.

So basically good luck finding one that looks like this unless it's a mature specimen? Would the offspring from this palm be identical?

Looks like a Phoenix rupicola.

I agree Steve but it's in an area that sees temps in the low 20s and high teens some winters.

Rupicola usually has longer and more arching fronds. But if there's been a bit of crossing anything might happen. Don't know the exact temperature tolerances for rupicola but I thought it was fairly low.

Beautiful palm! It does look a lot like rupicola. Its possible that it is a hybrid, but it definitely has some rupicola in it. Rupicolas are not very cold hardy, but they probably could survive a brief dip to the the low 20s with lots of damage (like you describe this one getting) and still manage to survive. It may be in a good microclimate and didnt get as cold as 18F, but slightly warmer. When it comes to that kind of weather every degree counds!
