You mentioned 'SFES'... it's a selection that I've sent to you in the past,
wondering if it might be polygamodioecious male... but you and I both have
determined that it probably is not.
The ortet is a chance seedling from Christian Co., KY, growing in a roadside
fenceline along KY 91, directly across the road from Sinking Fork Elementary
School (hence the SFES moniker). Most years, it produces about 80% small
(1") seedless fruits, and about 20% larger (1.5") fruits, containing a
single, plump, well-filled seed.

Hi Jackie,

You certainly have my permission and maybe I should expand upon the
explanation. I'm sure that Lucky and Betsy fully understand but it may be a
little too technical for newer, less experienced persimmon readers.
When I wrote that the thought went through my mind of writing a longer
article for Pomona and the Indiana nut and fruit growers and anyone else who
might wish to publish. But you can certainly let it go the way it is if you

Right now I'm very busy as last Friday we shipped almost 700 pounds to the
processor and yesterday the pickers picked another 400 pounds. I also have 3
small orders for pawpaw to ship today. I need to write a report for the
winter issue once harvest is over. I've not written a report as the persimmon
chair in several years.

Please remind me later on.
