I did a little research on this fig. I have found that it might be the same as "Rick's Calabria," one of my best producers this year. I got it from another member. The source of his tree and your cuttings sound identical - a large inground tree in a Pittsburgh, PA, suburb, originally from Calabria region of Italy. Fruit description and flavor profile are the same. Leaves are a match. Neither mother tree is ever protected in winter yet grows huge. That said, I would be willing to bet the same tree is the source of both the Unknown and Rick's Calabrias. It is an awesome fig.
