I have a question hope someone can help...

I have 3 Figs in my yard.

2 are originally branch transplants from the same "heirloom" variety that an ancestor originally planted in the 1920's .. Figs look similar to Brown turkey photos. Been there 12 years & are both doing fine , figs are ripe Sept or Oct most seasons in my climate. I never cover them in winter. Even in Some very harsh seasons, the canes may die back to the ground over winter, but by July they grow back to 5-7ft tall & loaded with immature fruit.. Other seasons, like this year, most canes survived the winter fine, & have leafed out ..

** The other Fig was given to us about 7-10 yrs ago, & is supposed to be a 'white fig' variety .. However it has never produced fruit, not even immature fruit ..

Canes get large, sometimes taller than the heirloom, & leaves look healthy .. Any Ideas??
