I've been experimenting with Figs for the past 7 years in the North East. Figs are actually native to the Sub-tropical areas such as the Mediterranean region. They prefer dry long summers and cool and wet winters. So not all varieties will do well in zone 6 or colder.
When choosing a variety to grow in this area, one should keep in mind to find a variety that ripens early enough before the temperature drop, and would tolerate the extreme cold.
Among many varieties that I've tried, only very few were my favorite for Flavor, production, and suitability.

I have great success growing the following varieties:
Brooklyn White *
Dark Portuguese *
Hardy Chicago

*those are my own named varieties.

I'm sure I'll be adding to this list over the years.

Does anyone have any other varieties that you would recommend?
