Most unusual fig here may as well be also the most common fig in the northeast US: Mt Etna, for all its especially robust qualities, including ripening time, cold resistance, productivity, aesthetics, reliable fruiting after dieback, first-rate flavor.
And Osborne Prolific for it’s reported genetic difference from Mediterranean figs.
Brooklyn White too. There’s something about it. Not the most premier fig, not the most rustic fig, not the most friendly fig though not unfriendly. It’s sneaky good, one of the most appealing if picked at the right time, with an unusual honey-berry blend, as they ripen here.
A case can be made that these figs all have unusual and unusually appealing qualities. There are many interesting and spectacular (and more-or-less redundant) figs. These seem a little more unusual than others here. That said, most varieties have an appealing peculiarity about them, which would tend to define the variety, being the distinction from other varieties that has preserved it through time.
LSU Purple is weird. Wuhan is weird. Lattarula is weird. San Miro Piro is weird. Etc. Weird good. Strangely good. Figs are odd. I’ve always felt that RdB has, somehow, an attitude, as compared to say the more matter of fact Mt Etna, though that may say more about the observer than about the observed. For as shapely as figs are they also almost always seem somewhat misshapen as well. You’re looking at something that seems like one thing and also its opposite. A fig is a delicate fruit with a hole in it, yet it hangs together. That seems unusual in general. Bugs (fig wasps) are supposed to fly into the fruit, and decay in the fruit, to enhance it, or to enable it to ripen in the first place, not to ruin it. Or, as with many figs, no infesting bugs are needed. Figs are odd fruits in general, it seems, and possibly only marginally so by variety.
Violet Sepor is unusual too (photos above).
Lots of fruits are odd though, in a wide variety of ways. I went into the snowy frozen woods late yesterday and picked sweet ripe, bright red, somehow juicy and nutty barberries (apologizing to the birds who eat them all winter). No fig can do that, hang sweet and bright on the bush through frozen months, nor can most other fruits, no matter how unusual. But other fruits like some persimmon and medlar require a freeze to sweeten. Seems unusual, from a certain perspective.
Mt Etna is the most unusual fig here, and the least. It’s the most premier fig here too, and among the least. It’s the most and the least unusual fig I grow.
