Castanea dentata 'Darling 4'

Title Image

American chestnut

FAMILY Fagaceae (Beech Family)
LANDSCAPE USES Darling 4 is a transgenic cultivar of the American chestnut developed by scientists at SUNY College of Environmental Science and Forestry in Syracuse, New York. In field tests it showed significantly enhanced resistance to chestnut blight. The species, Castanea dentata (American chestnut), is an upright tree developing a broad crown with wide spreading branches. Known to reach up to 100' tall and sometimes as wide. Leaves are alternate, oblong-lanceolate in shape, 5" to 8" long and 1 3/4" to 3" wide. Stems and buds are chestnut brown. Fruits are 2" to 3" in diameter covered with dense spines and containing 2 to 3 edible nuts. Once common over a great area of the eastern American forests, American chestnut has been decimated by a blight, (Cryphonectria parasitica) introduced approximately 1904 on the East Coast at New York. The blight spread quickly through the forests and in time completely encompassed the native range of this tree. Stump and root sprouts persist, growing from the remains of trees killed by the blight. These sprouts grow to roughly 20 feet tall and then the blight attacks them. Restoration of the species is of great interest and efforts are underway.
