Pinus resinosa
Red Pine
Mike's
Opinion
"
The common name Red Pine is derived from the reddish colour between the fissures of the bark. It is a native tree that can adapt fairly well to different conditions but is not salt tolerant. It does not really possess any stand-out features (other than attractive bark) and therefore is not used in the cultured landscape.
