Puerto Rico and Hawaii are large, and have very high mountains that do get quite chilly. Here, my island is so small (7 miles at the widest, by 28) that the warm sea keeps the nights well above 65 degrees. No chill there! But we are at similar latitudes.
All the zone stuff is about coldness, and how far north, and blah blah. I have yet to read about subtropical and tropical requirements. Even Logee's. Although I do have a book about Florida fruiting plants, and it has some that do well in different parts of that huge state.
I'm not quite wealthy enough to have a refrigerator just for some plants to live in for two months out of a year, booo. And I haven't been Up North in many years. I realized that I was not happy visiting there...
