* A rapidly growing deciduous hardwood tree.

* These are the sweetest seeds of any species in this genus

* A delicious oil can be extracted from the seed by crushing the nuts, boiling them in water and then skimming off the oil as it comes to the surface. It can be used as a topping for various puddings. more...

* The American Chestnut is a prolific bearer of nuts , usually with three nuts enclosed in each spiny green burr.

* The total number of chestnut trees in eastern North America was estimated at over three billion, and 25% of the trees in the Appalachian Mountains were American chestnut.
