Hi Jsacadura,
I'm in Zone7 . How can one explain that "Dauphine" is ripening the main crop with 3 to 5 figs per stem - so no figs were lost to lack of pollination.
My explanation is that people mislabeling trees or using wrong names leads to wrong information.
People then taking those informations for true, copying without verifying, in a book of 200 pages how could one verify all the informations, then just help spreading wrong informations.

The "Dauphine" that those papers are refering to might be the "Masui Dauphine" that is "Abicou" and is called "San Pietro" in Italy . Translate "San Pietro" and you'll have "San Pedro" in some cases, not always. Since you could translate that for the Saint and then you would translate it to "Saint Peter" ....

The real Dauphine, the french Dauphine is currently ripening her main crop here by me but still not in my garden for now. It is of the common type as far as I can.
I bought one last year, labelled "grise de Tarascon"; I'll see in two or three years was the outcome is for my tree - provided that it is not mislabeled.
So far the leaves of mine seem consistent with the other Dauphine that I know.
