Are you looking for figs for zone 6a, or 6b?
Zone 6 b; Violetta Bayernfeige, Hardy Hartford, Hardy Chicago, Sal's EL, Danny's Delight, Brooklyn White, Bornham's Diamond just to name a few of the better known ones.
6a Marseilles Black VS, LaRadek's English Brown Turkey, Hanc Mathies's English Brown Turkey, Sal's EL.
All of the above will need winter protection for the first three to seven years. Until they become mature. There are some F4F form members living in New Jersey and growing figs outside without serious winter protection.
We found that winter hardiness was only one thing one needs to understand, to grow figs in a zone 6. You will also need varieties that can handle early and late frost. Ripen early enough to beat the first frost. Resist rain and cool summers.
We found that no variety had all the attributes we wanted. But, if I had to make the choice of keeping only three, they would be Marseilles Black VS, most reliable. Sal's EL one of the sweetest. Hardy Hartford, the best taste.
Tips and tricks?: Start off with only varieties proven to be cold hardy. Read all the post on F4F. While your in the process of reading and learning, obtain a Marseilles Black VS, and plant it in a protected spot. It is the one we recommend the most for the beginner. Bend it to the ground, and cover with soil and protect from moisture for the first three years. Then when you leave it out side unprotected, at least mulch the root zone.
Hope that helps.
