Hello, I came upon a couple mature (seed producing) chestnut trees in Vancouver. I was reading up on the endangered American chestnut and was wondering if the trees I saw are C. sativa or C. dentata. The young leaves did not feel very hairy, while the older leaves have a little grittiness to the touch, but still not hairy. I'm quite sure they are not Chinese or Japanese chestnuts.
That's great! In the fall, I might collect some of the nuts and try planting them. Is the species fairly flexible in its requirements (e.g. sun/soil)?
