Eleocharis montevidensis - Giant Hair Grass

Eleocharis montevidensis – Giant Hair Grass

Giant Hair Grass (Eleocharis montevidensis) brings a sweeping, meadow-like elegance to the aquarium. Unlike its smaller cousin E. parvula, Giant Hair Grass grows tall and bold — its long, slender emerald-green blades swaying gently in the current, evoking the feeling of an underwater prairie. It's a stunning background or midground plant that adds height, movement, and a naturalistic softness to any planted layout.

Hardy and adaptable, it performs well across a range of water conditions and lighting levels, making it an excellent choice for both beginner and experienced aquascapers. Plant in groups for maximum visual impact, allowing the blades to form a lush, flowing stand that frames your hardscape beautifully.
