Riccardia chamedryfolia – a liverwort – is one of the best-looking mosses. It has spread throughout tropical Asia, and we discovered it at a small waterfall on Sulawesi. Riccardia has an incredibly intricate structure. Firm, reef-like, deep green shoots can be easily attached to driftwood and rocks. This is an easy moss under moderate light; CO2 is not essential but does encourage healthy, vital growth. Riccardia’s small size makes it suitable for Nano Cubes.
