Hygrophila Polysperma

Hygrophila Polysperma (Submersed)

Hygrophila Polysperma is one of the most popular and beginner-friendly stem plants in the aquarium hobby, known for its fast growth, hardy nature, and vibrant green foliage. Its dense growth and adaptability make it an excellent background plant for planted aquariums, community tanks, and natural aquascapes.

As a fast-growing stem plant, Hygrophila Polysperma helps absorb excess nutrients and improve aquarium stability, making it a fantastic choice for both beginner and experienced aquascapers. This submersed-grown specimen arrives already adapted to underwater aquarium conditions, allowing for easier transition and instant aquascape impact.

At N8 Aquatics, our plants are carefully quarantined before sale to help ensure they arrive healthy, clean, and pest-free.

Emersed vs Submersed — Which Grown Form Should You Choose?

Submersed plants are grown fully underwater and are already adapted to aquarium life, so they settle into a planted tank with minimal melt — the best pick for aquascapes and established aquariums.

Emersed plants are nursery-grown above the waterline, ideal for terrariums, paludariums and wabi-kusa. Submerged in an aquarium they typically melt back and regrow as submersed foliage — more so in low-tech tanks without added CO2 — but recover well with good lighting and nutrients.
