Rossyanka is most productive among the hybrids and has a unique taste between Kaki and American persimmon with no issue of fruits drop and very cold hardy to -20F. It is a keeper. Nikita’s Gift is very tasty somewhat firm ripened fruits but not that cold hardy only to -8F with lots of top died back. The draw back on NG is that it tends to drop fruits like crazy and not as productive as Rossyanka. My 2 1/2 years old 6 1/2 feet tall Kasandra has not fruited yet but it is suppose to be a very good sweet tasting Kaki like in taste just like the Great Wall Kaki as one of the parent and crossed with the F2 Rossyanka male.
