Nursery contributed plant descriptions

I know this picture is not in focus, but at least you get the idea; these Chestnut trees bear large nuts at a young age (many are bearing in the nursery row). The tree may get to be 35' and would be classified an attractive shade tree. Also you need two for pollenization unless you have a neighbor with a chestnut (Castanea). Don't mix this up with Aesculus--horsechestnut and not edible. zone 5
