Pinus resinosa


Red Pine




            Mike's Opinion

this is Mike

"

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.
