If you try to dig up a fig tree without the help of a small escavator you'll soon enough discover how they manage to survive in pretty rough climates.
My grandfather had on his farm an enormous fig tre: it must have been over 15ft tall, so much we used a boom truck to pick up figs, whole baskets of them. I have no idea what cultivar it was as I haven't seen it since. The fig skin ranged from dark violet to black with intensely red flesh. I've never tasted figs so sweet ever again: not even the much celebrated Smyrna figs of Turkey come close. In some favorable years those figs dripped sugary dew: they were that sweet and as you can imagine you had to contend with swarms of bugs and birds.
During a thunderstorm that fig tree was hit by lightning and we had to cut it down, but we left the stump in place to see if any shoots would come out of it, and surely enough they did.
However the new shoots struggled, so much we ended up cutting them as well, after which the stump went dead.
I have tried tracking down that fig cultivar for a while now, with no luck. I suspect it was an old French cultivar because my grandfather got a lot of fruit trees and vines from France. Could also be from Spain as he had some Quince trees sent from there, but I really don't know.
If anyone has an idea of what that fig tree can be, I'll gladly accept any suggestion!
