yup. I don't know. I hiked up into some areas North of town, I mean you got around 10 miles north of me and the saguaros can't survive, it gets too cold for them, and so far it seems that most of them are doing ok. The dying saguaro was set into motion before the cold, it was one of the moved ones.
As for the other plants most of my Opuntia are fine, and the others are just shriveled up and will look better in a few weeks or a month or so. When I saw how cold it got, I was worried because supposedly saguaros are only good to around 10F. Lower then that and they freeze and the cells rupture.
Here's to you, all you insidious creatures of green..er I mean cacti.
