Thank you for the welcome! The ones I got from the nursery are Commander Hay and Red Beauty. The ones I ordered are Pacific Rim, Just Plain Crazy and Poco Loco.
It gets down the 27-29F, and mostly in the low to mid 30's.
After reading here, I brought the ones I bought back outside, on a garden shelf. Hmmm, does anyone know if real chickens leave them alone? Our girls have free run of the backyard, so I'd have to keep that in mind.
I know it may be a challenge growing here, and probably even more so when we move to Tuscon in 3 1/2 years after I retire!
