Dead Tree
From Tolkien Gateway
The Dead Tree (Third Age 2852 – 3019; the snag stood for 147 years) was the last of the White Tree of Gondor, which died at the same time as Belecthor II the twenty-first Ruling Steward. For lack of a seedling, the Dead Tree was left standing in the courts of Minas Tirith until King Aragorn Elessar found a new seedling on Mount Mindolluin in 3019.
