String Moss

Leptodictyum riparium

Family: Amblystegiaceae

Ask Finn

A stringy, long-stranded moss with thin, delicate shoots that grow in loose, flowing tangles — giving it a wild, natural look unlike the denser Christmas or Java moss. Often used to create shaggy, overgrown effects on driftwood or as a hiding place for fry and shrimp. Also used in Wabi-kusa style arrangements. Grows faster than many mosses and can be difficult to manage if left untrimmed but is very undemanding.
