I'm in NYC and had one grown in a whiskey barrel for the first time I;ve tried,
and it did not recover the winter here at that time. It wasn't particularly
extra cold too. Now the ones I have are in much smaller pots like 12 to 14"
inches. I'm not sure they would last during a real bad winter. also, won't
they be exposed by snow and/or rain and be forced to grow? What zone is NYC?
