It would be nice if this were an exact science but it just would not be as fun.
I recognize that some identifications are obvious and that Herman's identification skills much better than most. I tend to avoid the name discussions because there are figs to be grown. More importantly, figs to be eaten.
Thanks for pointer to Frank's thread because I missed his notice to owners of his Petite Negri. When I read the thread, however, there was only anecdotal and no conclusive evidence that compelled me to think that Frank's tree was not Petite Negri and could be positively identified as Aubique Petite. I am certain that Frank thought about it, thus will ask him why he changed his mind.
Meanwhile, I have trees that are named VdB, VdB EL, Aubique Petite, and Petite Negri. I should be able to sample fruits from each fig this season and probably within a two day window because they appear to have similar traits. I sampled VdB and Petite Negri on the same day and they are similar (no doubt) but different (no doubt) to my taste buds. As you know well, the factors that could impact growth, flavor, productivity, and size are numerous: FMV, pot, potting media, water, sunlight, castings, fertilizer, mulch, limestone.
I believe that the right name adds value (see LSU ___, ___ de Bordeaux, ___ Black, Maltese ___). I also know that a great tasting fig is more valuable.
I will consider adding the weight parameter to my fig descriptions in the future and having a digital scale will make it easier to do so.
