What is the name of the sacred white tree associated with Gondor in Tolkien’s writings?

The sacred tree associated with Gondor is the White Tree of Gondor.

The White Tree is a symbol of Gondor’s kingship and the survival of its royal line. In The Lord of the Rings, a dead tree stands in the Court of the Fountain before the king’s return. Aragorn later finds a living sapling on Mount Mindolluin and brings it to the city.

The tree’s history reaches back through Númenor and the Elves. Tolkien’s mythology connects the White Tree of Gondor with Nimloth, the White Tree of Númenor, and ultimately with the sacred trees Telperion and Laurelin of Valinor. The line of descent gives the symbol both political and mythic significance.

The White Tree is not the same as the Mallorn trees of Lothlórien, whose leaves are golden. Its image appears on the banner of Gondor together with the crown and the seven stars, making it one of the clearest visual emblems of the kingdom.
