Echo Flowers are a type of flora found in Waterfall. They are named after their ability to repeat the last sounds they have been exposed to, similar to echoes, making them a potential lore device. Eventually, the sounds they emit become white noise.[1] Across the Waterfall area, the protagonist can hear monsters' conversations through them. Many Echo Flowers are silent in the Genocide Route.

Like most flora in Waterfall, Echo Flowers are blue and bio-luminescent. They have a large corolla with six lighter colored petals. Echo Flower plants have one tall stem, where an individual blossom grows.
