Niphredil was a small white flower of Doriath, and called the Star of the Earth.
Niphredil first bloomed in the forest of Neldoreth in Doriath to greet fair Lúthien when she was born. Together with the sun-star flower of Elanor, it also grew in Lothlórien on Cerin Amroth.. After the passing of King Elessar, Arwen laid herself to Cerin Amroth and died. Following this, niphredil and elanor bloomed no more east of the sea.
Niphredil is a Sindarin name for "Little pallor", from nipred ("pallor") and the ending il. The name may also mean "Snowdrop".
