In J. R. R. Tolkien's high fantasy universe of Middle-earth, the White Tree of Gondor stood as a symbol of Gondor in the Court of the Fountain in Minas Tirith. The White Tree also appears as a motif upon Gondor's flag and throughout its heraldry combined with the seven stars of the House of Elendil and the crown of the King.
The first White Tree of Gondor came from a fruit that Isildur, at great personal risk, managed to steal from Nimloth the Fair, the White Tree of Númenor, before it was destroyed at Sauron's insistence. He suffered many wounds at this mission, and he came near death, but when the first leaf opened in the spring, Isildur was healed of his wounds.
This sapling was brought to Middle-earth on Isildur's ship, and it was eventually planted in Minas Ithil before the house of Isildur. But when Sauron returned to Middle-earth, he launched a sudden attack that captured Minas Ithil, and he destroyed the White Tree.
Isildur escaped the capture of Minas Ithil, taking with him a sapling of the White Tree to Minas Anor where it was planted in the citadel courtyard in memory of his slain brother Anárion. This tree died in 1636 during the Great Plague.
A third sapling was planted in the year 1640 of the Third Age by King Tarondor. This one lasted until the year 2872 and the death of the Ruling Steward Belecthor II.
