I have been told by some well known collectors, who know their figs, that Kathleen's Black, just might be a very cold hardy sport of Black Mission.
I do not have Black Mission growing. So, I can not compare it to our Kathleen's Black. But, It sure acts like a Mission fig here in our zone 5b/6a. It's first two years here it froze back to the ground. That was after it was bent to the ground and covered. Then this last winter, it still lost 75 percent of it's top. It is with out a doubt, the most cold sensitive in ground fig we have.
I only keep it because Gene Hosey once told me that, once I tasted his Kathleen's Black, I would feed my Hardy Chicago to the pigs.
So, with an endorsement like that, I keep hoping it will become more adapted to our cold location.
But, for any one who is lucky enough to live in a zone 7 or warmer area, they are lucky that Gene brought this, maybe Black Mission, to our attention.
