I'm not surprised. You are much closer into phoenix than I am. Don't you remember those icicles I posted hanging from my hanging baskets this winter, over a foot long? Or the bird bath, six inches deep that was frozen sold. I also had ice on the yard, and lots of frost.
Also, your yard is smaller, and your houses are closer together. I have a huge park across the street, the houses are not so congested. There is still some farmland out here. My Rangoon Creeper also froze to the ground, fortunately it is coming up from the roots. I was hoping that would happen with the Dombeya, but it did not. :(
