It needs a long sustained hot season. First cold days really affects ripening thereafter. They will still "ripen" but will not have the flavor and sweetness. I got it as an air-layer that was about 12" tall, somewhere around 15+ years ago. It is now about 72" tall, and will get pruned to about 36" in January. I had maybe 3 dozen good figs at the beginning of the season, before we had a brief cold snap in Sept that was enough to mutate the ripening process. I've probably had 100 or so "ripen" since then, though many have split. It is the King of Flavor, but quirky to grow and ripen successfully. I have a couple other varieties which may prove to be similar and/or as good, but will need a few more years of evaluation.
