Hello, Your topic is “figs types”;
Ficus Carica (figs) types are; Capri (male figs), Smyrna, san pedro and common.
For Zone 6b only common and a few san pedro figs are of interest.
The fig cultivars you should attempt really depends on whether you plan to grow them in containers or in the ground.
If growing in ground then your climate zone really matters and only a few common figs are known to be successful in zone 6.
There are a number of discussions on this topic (try the search) and basically all point to mount etna figs, rdb, lattarula, florea and a few others.
But If you plan to grow your figs in containers then the whole common and san pedro type fig world opens up for you. Any fig variety of these types can be grown in your zone. For some of the late ripeners a greenhouse (or sun room) will help to extend the season to ensure your figs have enough time to ripen.
