That’s a very interesting description, thanks for sharing! A google image search for “Shibugaki” shows more elongated, smaller fruit than those in the video of Kuroama fruit shared by @castanea. Also, the flesh color of the Shibugaki pictures isn’t dark at all. The darker flesh may only result from pollination like in PVNA cultivars. I would still like to know if Kuroama is PVNA as well.
Does anyone know if dark skinned “kuro” kaki have dark flesh as well? Are the kuro kaki fruit PCA, PVNA, or PVA? Here was a thread about it a while back, and apparently One Green World is now selling a black persimmon they call “Raven”.
