I'm in Arizona, and have had mixed results with some of those in summer. I had an in ground raja and goldfinger burn to a crisp last summer, while namwah did OK.

The namwah is still going strong this year, and well as a red (planted mid summer - a bad idea in the desert) , and a basjoo (that has now been split several times). I also have a manzano in a pot, in full sun that went from a tiny corn to about 6 ft over the summer (going in ground in spring).

For me the key has been planting depth. For me, a planting at a depth of a foot or more means they survive the summer, with little burn, anything less and they don't retain moisture at 110 plus. In my non scientific tests, at that temperature, soil moisture is almost non present in the top 6 inches or so of soil (even with them on the drip morning and night, the first few inches actually feel hot to the touch as well - probably to the detriment of the root system). I buried soaker hose with them at that foot depth, and that becomes my primary watering source in the summer.
