The singing fern originated from Corellia, specifically the Agrilat Region, a marshy area on that planet located within the Core Worlds. This fern was a type of crystal plant; like the majority of plant species found in the Agrilat Region, it consisted of a combination of tough, compact silica and organic substances, resulting in a crystalline aesthetic. A unique characteristic of singing ferns was their ability to both absorb and emit a gentle light.
Fantasy Flight Games included the singing fern in Suns of Fortune, a sourcebook from 2014 designed for the Star Wars Roleplaying game Star Wars: Edge of the Empire.
