The Castanea Dentata x Mollissima - Hybrid American Chestnut tree is the result in the search for a blight-resistant chestnut through a breeding program for eventual reforestation. Because the original American Chestnut was near extinction due to a fatal, quick spreading fungal infection in the 1950's, this hybrid was created to not only be more disease hardy but keep all the characteristics of the original chestnut tree.

The leaves to this deciduous¬†Castanea Dentata¬†"Hybrid" - Hybrid American Chestnut¬†tree are a matte green and¬†lanceolate-shaped with prominent teeth, these later turn to shades of yellow, gold or brown during autumn months. Blooms¬†creamy-white long catkins That can grow 4‚ÄĚ to 8" in the summer and release a sweet fragrance.¬†Once pollinated¬†cluster¬†of sharp, spiny green bur or cupule emerge turn to a yellowish-brown once mature. Inside are multiple edible nuts that have a dark brown shiny husk, flattened side and pointed edge with a creamy-white spongey texture and buttery, sweet, nutty flavor.

Hybrid American Chestnut Tree

Widely used at the turn of the 20th century; the fruit fattened up livestock, and the timber from a single tree filled entire railroad carts. But in the early 1900's a lethal, fast-spreading fungus was accidentally introduced while importing trees known as Chestnut Blight, and our native trees were highly susceptible to this new type of disease. By the 1950's, the once large population dwindled to an alarming few saplings that were also diseased. Amid the news, a breeding program was developed to create a disease hardy chestnut that would still have the characteristics of the chestnut that once covered all Eastern hardwood forests. Due to their efforts, a hybrid was made using the disease-resistant Chinese Chestnut, allowing for promising reforestation efforts and the discovery of a few surviving old American Chestnuts that are still standing.
