Dark Tree

The 'Dark Tree' is an abstract term used by Tolkien in his fragment of a story The New Shadow (Part IV of The Peoples of Middle-earth).

Dark Tree is a description of the growing threat of evil in Middle Earth - its roots can never be fully destroyed so that evil once again arises if the 'tree' is left untended or unwatched.

'Dark Tree' is a term used by Borlas in the The New Shadow in his conversation with Saelon.
