Dwarf Hairgrass
Eleocharis parvula
Family: Cyperaceae
📍 Worldwide temperate & tropical
Dwarf hairgrass forms a lush, grass-like carpet in the foreground of aquascapes. It requires moderate to high light and injected CO2 to spread effectively, otherwise growth is sparse and slow. Regular trimming encourages lateral runners and a denser mat.
