Hello everyone, I am new to the board.

My grandfather currently grows 3 fig trees in New York City and I would like to add some more to the yard.  I was wondering what fig trees everyone would recommend for this climate that produce large figs and are sweet (they can be any color). I was actually looking at Celestial's and Desert Kings but this is not set in stone. 

Also, because of limited space, I was looking to get two different varieties and plant them in the same hole. This was currently done in my yard by my grandfather and another person told me that they should be of the same hardiness and growth rate.

Any Suggestions? Thanks in advance for your help.
