Also called Simbelmynë.

Evermind was the fair white flowers that grew over the barrows of the kings of the land of Rohan.

The flowers were like glittering crystals of snow that blossomed in all seasons, glinting away with starlight on the tombs of these kings. And to the Rohirrim and common Men alike the white flowers on the green swards were always a reminder of the power of the strong kings of the Mark.
