For the history buffs…found this to be an interesting read.
-Because they held competitions for farmers to submit the best examples of each tree crop, often published in rural newspapers, they were able to crowdsource the best genetics from across the Eastern Seaboard. Many of the finalist submissions became named cultivars that were propagated by Hershey and others for decades to come. These often came from old farmsteads in the South that had preserved the trees from pre-industrial times - farmsteads that often have since been paved over and developed.
“Fall of ‘65 with no rain - grass growth at a “stall”, 60 young [persimmon] trees fed our 25 herd 2 months, grew and fattened; 15 sheep 4 weeks, from late September till last week of November, then started to look for hay. Think of it. With little loss of hay and pasture crop in the orchard this tremendous crop of persimmons, 35% sugar, 10% protein plus many other feed elements; plus the potent oil and protein in seed it really excites you. Can you afford to slug along without them?”

I got email from Zach Elfers saying that most of Hershey’s varieties are safely preserved in other places now, thanks to heroic efforts of a few people, along with a NNGA grant to establish a preservation orchard. Here’s his email:
" Yes, John Hershey’s varieties have been preserved via grafting and these varieties are being actively planted out at various preserved locations, as well as through nursery sales. I offer some of them through my nursery in Pennsylvania at http://www.futureforestplants.com and Buzz Ferver in Vermont is offering much of the Hershey germplasm through his nursery at http://www.perfectcircle.farm.
Outside of Easton, PA our friend/colleague Louise Bugbee has secured a “Hershey Nursery North” permanent publically-accessible tree crops arboretum at Louise Moore Park. She received a grant from NNGA to help secure the funds for the project. This fall we broke ground and planted many of the hickory, black walnut, persimmon, mulberry, and honey locust selections, and plan to continue adding to the collection each year.
Keep in mind, the varieties that have been preserved are those still present around Downingtown or still available through the nursery trade. It’s been a detective process to identify to name the unlabeled trees remaining at Hershey’s old farm. Unfortunately some varieties he listed through old nursery catalogs have been lost / we haven’t yet tracked them all down. But what we have identified and preserved is substantial! We also have ad-hoc names for some of Hershey’s better selections that we can’t identify precisely to name, as is the case for many of the persimmons."
Additionally, John Hershey planted out a lot of seedling trees back in his day so gleaning from the remnants of his farm, collectively we have introduced several brand-new varieties including honey locust, mulberry, black walnut, chestnut, and persimmon.
