All the many succulents are fascinating; I developed a real appreciation for them when we lived in Phoenix, AZ for a while. Some of them actually had to come IN during the summer because the relentless heat and very low humidity was too much for them. When I say "heat," I mean daily 40-45+ degrees...

Egads! That is way too hot. For humans, too.
I get my succulents out of the sun once the temps go over 25. In nature, most of them grow in the shade of rocks or other plants and roasting really isn't good for them
