They are pretty close cousins to Allegheny Chinquipins. I would expect performance to be similar. I still have a few ACs on my deck that I overwintered. The last chestnut family tree I'm working with is the Seguin. I got a couple I started from seed. The Wildlife group has not sold them for the last couple years. I bought two from OKIOS last year, but it wasn't worth it. They were expensive and very tiny. One is leafing out right now but the other was already killed by squirrels. Seems no matter how many I shoot, more take there place in the neighborhood. Good Luck with the OCs. They are pretty rare these days.
Thanks,
Jack
