South Pacific...they love that area, humid and hot! Plumerias thrive so well in my homeland which is in Southeast Asia with all the typhoons, flooding and all. You are right sun and humidity is so intense there. That is why growing up our mantra there was water your plants everyday. It took me awhile to re-adjust what I know with plant care when we moved to a four season country. They grow majestically there.
I thought you are now currently in Raleigh, NC, since that is what is showing on your profile.
