NYC's zone 7 winters are quite mild in terms of low nighttime temps, but not so mild in terms of clouds, moisture, and colder days. These may be the biggest challenges to pomegranate, which likes it drier and sunnier with mild days offsetting the cold nights.

In any event, there are plenty of folks having success in similar and even colder climates. One poster by the name of Bass grows lots of pomegranates in PA. Lee Reich is experimenting with them in Western NY State. Do a search on this forum for the many many threads related to cold hardy pomegranates.

Another challenge will be getting the plants to fruit, since they take a very long season of ideally hot dry summer weather to ripen...

Hope this helps a bit, and good luck...

Two of the 'Russian' selections, Salavatski & Kazake, are currently looking like the best bets for pushing the envelope; or at least, they've probably been trialed by more folks in areas not typically considered to be hospitable to pom culture.
Bass has grown both - and may be offering them from his Trees of Joy Nursery - check out his website

Thanx for the info ... Now at least I see a possibility.
