The American chestnut is a critically endangered native species of chestnut tree. Due to the chestnut blight fungus that passed from Japanese chestnut trees in the early 1900s, American chestnuts have a difficult time surviving to adulthood. Although once an abundant and staple cash crop, providing food for humans and animals alike and supplying beautiful, reddish brown wood, the American chestnut population was reduced to 1-10% of its original population and has not recovered. Efforts are being made nationwide to restore the population through crossbreeding with much more fungus-resistant chestnuts, such as Japanese and Chinese chestnuts. HCC’s chestnuts are crossbred with Chinese chestnuts.
American chestnuts are fast-growing, deciduous trees. In the autumn, they produce fruit covered in needle-like burrs, which contain shiny brown nuts that are edible and mildly sweet when cooked.
In Congressional Cemetery, there are 6 American chestnuts located in the northeastern section, near the public vault. They were planted by the American Chestnut Foundation’s ongoing restoration project to help restore the DC American chestnut population wiped out by the blight.
