My NdC tree came directly from a friend in the UK. This year, I started collect other folks KBs and NdC sold on eBay. Today, I have 3 NC and 3 KBs. One KB is in the ground the others in contaners. This year I got lots of figs from my NdC. I got zero figs from my KBs. All were pinched too. About 4 weeks ago, I pulled one KB inside. It will fruit next year.
I think there is a HUGE mix up with these 2 figs. I do know one thing, my NdC is one of my best tasting black figs in my collection.
