The White Tree of Gondor acts as a symbol of hope, and when it appears to have withered and died in the courtyard of Minas Tirith’s Citadel, it stands as a sign that Men are on the brink of hopelessness. The fate of Gondor’s people appears to be bound to the fate of the White Tree, as suggested by their livery which bears the tree’s image. When Aragorn claims kingship, he wrestles with the threat of his line ending and of Gondor falling into ruin. However, Gandalf takes him to a secret mountain field to show him that a White Tree sapling, a descendant of the current White Tree in the courtyard, is growing, by some miracle, in the snow. Aragorn takes this sapling and replaces the withered Tree with it to signify that his descendancy, and Gondor’s future, have a strong hope of flourishing.
The White Tree Quotes in The Return of the King
“Turn your face from the green world, and look where all seems barren and cold!” said Gandalf.
Then Aragorn turned, and there was a stony slope behind him running down from the skirts of the snow; and as he looked he was aware that alone there in the waste a growing thing stood. And he climbed to it, and saw that out of the very edge of the snow there sprang a sapling tree no more than three foot high. Already it had put forth young leaves long and shapely, dark above and silver beneath, and upon its slender crown it bore one small cluster of flowers whose white petals shone like the sunlit snow.
