Cool Fact:
There were actually four White
Trees of
Gondor. The original seedling, saved from the Downfall by
Isildur, was planted in
Minas Ithil at the end of the 2nd Age. After
Sauron soon thereafter re-gathered his strength, he returned to
Middle-Earth and burned this tree, the 1st White Tree. At the start of the 3rd Age, after the defense of the Last Alliance, Isildur planted a sapling from the first tree in Minas
Arnor in memory of his brother Anárion. This 2nd White Tree survived until mid-way through the 3rd Age, when the Great Plague swept through Gondor, under King Telemnar. A sapling was saved by King Tarondor and grew in
Minas Tirith until the end of the 3rd Age, when it died under the Stewardship of Belecthor II. No seedling was found, and it was said that the 3rd White Tree would stand wilted until the coming of the King. For 147 years, there would be no
White Tree of Gondor.
Fifty-nine years after the death of the 3rd White Tree,
Aragorn the
Dúnadan would be born in Gondor. After his unification of the Two
Realms and subsequent coronation,
King Elessar, under council from
Olórin, found a small sapling in the
mountains surrounding Minas Tirith. He planted this, 4th White Tree in the place of the withered 3rd White Tree, which was in turn placed in the Tombs of the
Kings. This 4th White Tree, Sixth in the line of Galathilion of Tuna, would flourish in Gondor for some years, but ultimately fade with the coming darkness.
My opinion:
The Palantíri, on one hand, are the actual jewels crafted by
Fëanor in the
Undying Lands. Of the unknown number that were originally created, we know there were 7 of them brought into Middle-Earth by
Elendil, in addition to the Master-Stone on Tol Eressëa.
The White Tree, on the other hand, was descended from Galathilion, the tree created by
Yavanna in
Tirion in the image of Telperion.
Due to the fact that this tree was made personally by the
Vala responsible for creating all green things within
Arda, Yavanna, I must place its value over the seeing-gems of Fëanor, however great of a craftsman he be.
