Plant Profile
Common Name: Helanthium Tenellum Broad Leaf
Helanthium Tenellum Broad Leaf brings a really cool, hybrid aesthetic to your aquascape, looking almost like a perfect mashup between dwarf hair grass and micro swords. The broad leaf variant features thicker, distinct leaves that visually resemble Dwarf Sagittaria. It spreads out across your substrate by sending out energetic lateral runners, creating a lush, dynamic texture over your foreground. Because it stays relatively compact, it’s a brilliant foreground option for larger setups, but can easily double as a short, clean background plant for smaller nano tanks.
Tissue Culture cups ensure your aquascape gets a super clean starting point. Lab‑grown and fully sterile, it arrives without pests, snails, duckweed, or any unwanted algae. It’s the go‑to option for anyone who wants peace of mind when adding fresh greenery to a carefully maintained setup.
Key Features & Benefits
- Thicker, broad-bladed grass foliage that bridges the gap between hairgrass and sword plants.
- Versatile growth habit fills in a foreground carpet beautifully or serves as a neat background accent in nano tanks.
Care & Planting Instructions
- Thoroughly wash away the nutrient gel from the roots with your fingers before parting it out into manageable portions and planting.
- Use a dry start method or Wabi Kusa setup to give its root system plenty of time to firmly anchor into the substrate before you flood the tank.
- Maintain stable aquarium parameters and avoid drastic shifts in water quality to prevent your new grass from melting.
- Provide medium to high lighting and inject pressurized CO2 to supercharge its density and growth rate, keeping it low and compact.
- Master the basics by learning how to properly grow aquarium carpet plants to ensure your new layout fills in quickly.

Frequently Asked Questions
1. How do I plant Helanthium Tenellum Broad Leaf tissue culture?
Use fine-tip pinsettes to push the roots deeply into nutrient-dense aquasoil. Space clumps 1 inch apart to allow runners room to spread.
2. Can Helanthium Tenellum Broad Leaf grow in a low-tech tank without CO2?
Yes. It is a hardy, adaptable plant that will grow and send out runners in low-tech setups. However, under higher lighting and pressurized CO2, the plant spreads much faster, stays lower to the ground, and can develop attractive reddish-pink hues on its leaf tips.
3. How does the 'Broad Leaf' variant differ from standard Helanthium Tenellum?
The Broad Leaf variant produces wider, thicker blades resembling a mini sword plant (Dwarf Sagittaria).
