good job. Yes American Chestnut. You wouldn't believe how many guys at work said sea urchin.
.
I planted this tree about 10 years ago and this is the first time it ever put out fruit, nuts. It is a special disease resistant American Chestnut variety . Hard to believe that once it was the most abundant food and timber tree in the east. Quoting "within a 40 year span from 1904 over 30 million acres of them were killed making it the largest ecological disaster in American history" that is like 3 billion trees and there are no more than 100 original American Chestnuts alive today as a few had resistance to the blight. They said that in their haste back then that panic logging probably destroyed many healthy resistant ones but they wanted to get the valuable lumber out of them before they died so many were killed that probably could have weathered the blight. Even to this day they are finding solitary trees out in the wild still alive. They have cross bred a couple of those remaining trees around 1962 with a Chinese variety to make it disease resistant and the hybrid I have. Pretty cool stuff.
