Seregon was a plant with red flowers that grew on Amon Rûdh during the First Age of the Middle-earth. In the First Age, Túrin and his outlaw band Gaurwaith were led by Mîm the dwarf to his home at Amon Rûdh. Seregon and aeglos grew there, and seregon mantled the stone. Androg, Túrin's companion, described the view as "blood on the hill-top".
