Silent Hill f uses the White Claudia flower to connect to the series' lore

Silent Hill f connects to the series through the hallucinogenic flower White Claudia, known as Hakkokusou in the game. The flower's seeds and refined form, Aglaophotis, have been used by cultists and characters in previous Silent Hill games for their mind-altering properties. This connection is revealed through in-game documents and item descriptions. Silent Hill f explores themes of psychosis and altered reality, mirroring the psychological horror central to the franchise, and is considered a strong entry in the series.
