PLANT OVERVIEW

About Coral Moss

A dense, coral-like liverwort for detailed hardscape.

Coral Moss (a Riccardia liverwort, often sold as Mini Pellia) forms tight, branching, coral-like cushions of deep green. It's slower and a bit more demanding than true mosses, benefiting from CO2 and clean water, and glues beautifully onto stone and wood for detail work.
