Acer davidii, Acer pennsylvanicum
The snakebark maples are named for their white striped bark which becomes rough and cracked with age. Acer davidii, Pere David’s maple, is a Chinese maple which has seen successful use in bonsai. It is a good tree for high elevations, as it will grow at up to 3000 ft. Acer pennsylvanicum is the only snakebark maple native to the US. It is easily located on the east coast, but rarely found on the other side of the Alleghenies.
