Ed, here is where size really does not matter.
Taking my big tree as an example. I have fruits of all sizes and shapes, some more like apples, others like pears with long necks, some are purple on the outside, but lately without much light, they are green with little tint of purple. Even the pulp, most of it is amber, but here and there I have a tint of pink.
Even though I have it for 20 plus years, if the figs get mixed up with others... I would not be able to tell it is from my tree, except for the taste which seems to be the only thing all fruits have in common, wait not even that, some are sweeter than others.
Furthermore, even those from nurseries come mislabled, so, who is to know what is what?
