You didn’t change the list to reflect my input. Maybe you didn’t believe me? Or maybe you were confused by Dax’s recent claim that NB-02 and NB-21 are siblings of JT-02, which they are not. So here’re the descriptions from England’s catalogue:
Zima khurma =NB-02 Persimmon bred out of Nikitskaya Bordovaya, cold hardy and good producer of orange medium to large size fruit that ripens Late-season on a semi-vigorous tree. Has low spreading growth habit and is a beautiful specimen in the fall. Trees are very cold hardy tested down to minus -16.4 F for a long time. This cultivar was bred in Japan and brought to America by Jerry Lehman of Terre Haute, Indiana. Zone 5b to ZONE 8, tested to -16 F.
Edit: In another thread, Dax wrote: << NB-02 aka Zima Kurma has the genetics of: Nikita’s Gift x (kaki) Taishu. >>. So at least for that moment, his understanding matched mine.
See. Persimmon Cold Hardiness Resource - #11 by Barkslip
