Same zones this time.

If I move, it will be to the southeast until I hit water. But I don't see leaving N.C. Just want to live on beach! But the winter coldness to me is the determining factor.

To me there is a big difference between your zone 7
and NYC zone 7,maybe something like njoasis pointed out (where
they take days over 80F etc(???) into consideration) would work.

It would be easy for another map system to get complicated way fast!

Locally, our summers are warm enough for such subtropicals as Magnolia grandiflora, Crape Myrtles, and Needle Palms. Early Spring can be really crappy though (rainy, raw and cloudy weather) because of cold off shore water temps. 'Spring' seems like the shortest season with a rapid transition into hot and humid weather. Best season is the Fall which tends to be sunny, mild, dry and long. Another gardening consideration (aside from absolute lows, and heat zones (average number of days above 86 F.), is the frost-free season. So while I'm not thrilled with cold Marches and sometimes chilly Aprils--frost free weather continues until LATE in the year and the average number of frost-free days is over 200.--I had my Queen palms out until early December last year and can recall seeing geraniums and impatients in bloom in backyard gardens in NYC also into December.--I might add that after the past year which featured an incredibly LONG, HOT, AND DRY summer and an equally awful COLD and SNOWY Winter, I do consider the benefits of life in a less extreme climate.

Interesting-sounds like Trachys would like it most of the time!
