Cape May is an interesting location regarding climate. I read it is the mildest spot in that part of the US East coast, which is logical due to the peninsular position. Is it possible to grow subtropical plants there? I guess not, I found the northernmost point to reliably grow citrus plants or palm trees is Virginia Beach - although I don't know how well such plants are doing there now after the last winter in the Eastern US. (Sorry for the OT post).
