I wouldn't bother with pure American chestnuts quite yet, as I am not aware of any that are commercially available and blight resistant. The breeding and technology is advancing quickly and hopefully I will be able to plant some in my lifetime.
Our state forestry nursery grows some Chinese x American hybrids and they are close to 4' tall as 1 year old bare root seedlings. I have had better success with bare roots than potted stock.
They sell out fast though.
As far as what to plant for mast, diversity, diversity, diversity.
