Simbelmynë

Simbelmynë Simbelmynë (Old English for 'evermind') is a white flower that grows in Rohan primarily on the grave mounds of the Kings of Rohan[1], and most thickly on the burial mound of Helm Hammerhand[2]. The flower is also called evermind, uilos ('snow white'), and alfirin ('immortal') because it blooms all year long. This flower was also found growing in the grass at Gondolin[3] and at the tomb of Elendil.[4]

Legolas also uses the name 'alfirin' to refer to an apparently different type of flower, described as "golden bells", which could be found in Lebennin.[5]
