Glad to hear your plants are doing fine...
Below is a list of kaki and asimina that was propagated this season.
The mulnerries that are available are: Pakistan, Rupp's roumanian",
Saharanpur, Lavendel, Illinois everbearing, " Sugar cube" and Morus
nigra "Aalst". There are also a very limited number of a hybrid
(Morus macroura) x Morus alba which has almost the same fruiting
as "Pakistan" but which is much hardier.

The Pakistan you bought last year is not the hybrid, it is a hardier bud
mutation of the true Pakistan which I discovered after a severe spring
frost a few years ago.
