Do you see where I live? Temps daytime in mid 90's summer. Nighttime 75-85 or so. Last winter we had an exceptionally cold winter. It got to 32 1/2 in the GH and everything, including the Phals were OK.
Just don't let it get too much direct sun. The conventional wisdom, as I understand it, is that the thin leaved plants tolerate less sun. Morning or late afternoon sun but not midday in our climates.
