PLANT OVERVIEW

About Lilaeopsis mauritiana

A hardy grassy carpet, thicker-bladed than dwarf hairgrass.

Lilaeopsis mauritiana forms a short, grass-like carpet with slightly thicker blades than hairgrass, spreading by runners. It carpets faster with CO2 and good light but is forgiving enough to fill in slowly in simpler setups.
