Castanea dentata (American chestnut)
Cressler, Alan

Castanea dentata

Castanea dentata (Marshall) Borkh.

American Chestnut

Fagaceae (Beech Family)

Synonym(s): Castanea americana

USDA Symbol: cade12

USDA Native Status: L48 (N), CAN (N)

Formerly a large tree with a massive trunk and a broad, rounded, dense crown; now found mostly as small sprouts from base of long-dead trees.

American Chestnut is gone from the forests, a victim of the chestnut blight caused by an introduced fungus. This disease began in New York City in 1904, spread rapidly, and within 40 years had virtually wiped out this once abundant species. Fortunately, there is no threat of extinction; sprouts continue from roots until killed back by the blight, and cultivated trees grow in western states and other areas where the parasite is absent. Blight-resistant chestnuts such as hybrids between American and Chinese species are being developed for ornament, shade, and wildlife. The wood of this species was once the main domestic source of tannin, the edible chestnuts were a commercial crop, and the leaves were used in home medicines.
