Hi Antonio:There is only one dark cultivar that compare with it,in quality and flavor ,if it wouldn't be so infected with fig mosaic virus.
And that is Burnisotte from UCDavis collection.
But in owr climate it will never produce fruit to be close to potential because of the FMV infection ,as the tree can't fight the Winters here.
I collaborated with other collectors,and I got in trade 2 other Burnisotte from Sources other than UCDavis ,in the hope to find a healthy cultivar.
I grew Them and they turned out to be inferior hybrids making some brown fruits,of mediocre quality.
So I am back to square one!.
Yet recently,I found proof that Burjasotte Noire (Violette de Sollies)is the cultivar that is identical to UCD Barnisotte,and It is commercially grown in France,and possibly those are healthy cultivars.
But I could not find a source to get cuttings.
Here it is how a contender to Kathleen Black look!
This fig is not identical to Kathleen black at all,but is the only one that is on the same level in quality flavor,cold & rain resistance,sweetness etc.
So if you aquire a Burjasotte noire from France,I am intereste to get a cutting from you.
Till then Kathleen Black is the Dark King,just like Adriatic Jh is the White King!
