American Chestnut
(Wide & Flat: Alternate Arrangement) |
| Formerly the most common and arguably the most valuable tree in
Pennsylvania for both its wood and nuts. It now persists as stump sprouts and
small trees due to the chestnut bark disease commonly called chestnut blight.
Chinese chestnut, Castanea mollissima Blume is planted for its 1" nuts. Its
leaves are shorter, up to 6" long and pubescent beneath. Chinese chestnut
is resistant to chestnut blight. |
