Laurelin

In J. R. R. Tolkien's legendarium, the Two Trees of Valinor are Telperion and Laurelin, the Silver Tree and the Gold that brought light to the Land of the Valar in ancient times. In Tolkien's fiction, Valinor was a paradisiacal realm also known as the Undying Lands where angelic beings lived. The Two Trees were apparently of enormous stature, and their dew was of a pure and magical light in liquid form. They were destroyed by Ungoliant at Melkor's behest, but their last flower and fruit were made by the Valar into the Moon and the Sun.

They are said to have been a kind of cherry tree, with leaves resembling a beech.

The first sources of light for all of Arda were two enormous Lamps: Illuin, the silver one to the north and Ormal, the golden one to the south. These were cast down and destroyed by Melkor. As a result of this, a large inland sea was formed in the place where in the past had been the mountain of Helcar, which held Illuin. The sea was named Helcar as well, and it was alongside an arm of this sea, known as Cuiviénen, the Waters of Awakening, that the Elves arose. Afterward, the Valar went to Valinor, and Yavanna sang into existence the Two Trees, silver Telperion and golden Laurelin shedding light comparable to moon and sun. Telperion was referred to as male and Laurelin female. The Trees sat on the hill Ezellohar located outside Valimar. They grew in the presence of all of the Valar, watered by the tears of Nienna.
