Yes, I do the same too James, we also get extremely dry here too, like 6 to 7 months no rain, but this plant thrives and enjoys the heat and direct sun nicely. I just don't get the blooms anymore when it starts hitting upper 90's. I get the blooms in late Spring to early summer. It loves a good watering in summer, I guess it compensates for our extremely dry and low humidity area.
My adeniums are still hiding indoors though. I am waiting for overnights to be stable 50F and higher before I bring them out slowly. So it is still by my south facing window.
