Yes, I...know...all...that.
Read the text, and think about what's going on. Many of his descriptions were second-hand. There are errors. Please don't get me wrong, I'm a fruit fanatic. I have old books from people just like Condit, like Popenoe, Fairchild, and Morton, and they all have their issues. You have a benchmark. It's growing right there in UCD, and grows exactly the fig people want. You don't need the book. You want the fig that tastes as good as that particular Black Ischia, not any accurate Black Ischia, which may well be some other fig not as delightful.
Cheez, if figs were as generally as good as these Provençal and Neapolitan varieties, I would have been much more interested in them as something other than an easy to grow fruit and would have many more trees! But I don't, and a good reason why is the incredible confusion that surrounds varietal info, and the sheer plasticity of pheonomic expression. If I wanted to, and I had the camera and all, I could go outside now, and pick leaves that are exactly the same as the ones in the pictures Jason uploaded. It has entire, three, five, and seven lobes all in that tree, both of them (and Ischia is related to the Bordeaux varieties). The breba season had fruits that look a whole lot like Barnisotte and Barbentane, and the long, droopy fruit that BLB, among others, got as brebas, are a rarity. The two once grew differently, and now grow more or less the same. Figs are confusing. So once you hit close enough for government work, well, it's time to put down the book, and look at the fig.
