Tolkien was a nut for pedigrees and complex lineages – the guy literally traced a direct line from Elros, the first king of Númenor, straight to Aragorn, who lives over six thousand years later. Characters like Elrond and Galadriel also have intricately detailed and complex family connections. And yes, the author put that lineage emphasis on his trees as well – and we’re not referring to Ents here (in fact, they’re surprisingly underdeveloped as far as family structure goes). We speak of the White Tree of Númenor, a tree called Nimloth.
“The Silmarillion” describes the emergence of Nimloth in the typically name-heavy Tolkien language, and says that elves would visit Númenor from Valinor to the west early in the history of the island and bring gifts. “And a seedling they brought of Celeborn, the White Tree, which grew amidst Eressëa, and that again was a seedling of Galathilion, the Tree of Túna, the image of Telperion, which Yavanna gave to the Eldar in the Blessed Realm. ” Without going into too much detail, this description traces the lineage of this White Tree directly to the silvery glowing tree that gives light to Valinor (and which Morgoth destroys at the beginning of the prologue of The Rings of Power). In other words , it has a pedigree that even Treebeard would be jealous of.
Finally, Nimloth’s existence is threatened by a series of events that we’re not detailing to avoid too many spoilers. Before anything bad happens, however, none other than our boy Isildur sneaks into the palace grounds and steals one of its fruits, saving the sacred tree in the process.
