Nymphoides Aquatica / Banana Plant
Plant Profile
The Banana Plant is a charmingly distinct floating plant with rounded, heart-shaped leaves anchored by a cluster of swollen green tubers that look just like a tiny bunch of bananas. What makes these aquarium floaters so versatile is their dual nature: you can leave them to float freely on the water surface or gently rest them on your substrate to anchor as midground accents. Left to float, their long stems quickly shoot upward to form a canopy of miniature lily pads across the top of your tank, occasionally even blossoming with delicate white flowers. That makes them a fantastic, resilient choice for community aquariums, low-tech scapes, and paludariums where their vibrant green tubers pop dramatically against dark substrate.
Key Features & Benefits
- Banana-shaped tuber clusters create an eye-catching focal point near the substrate or floating at the surface.
- Fast-growing lily pad canopy provides a soothing overhead shade layer that helps keep nuisance algae in check.
- Absorbs excess nitrates and biological waste to support a healthy water column.
Care & Planting Instructions
- Rest the banana tubers directly on top of your substrate, ensuring you do not bury them more than 1/4 an inch deep to prevent tuber rot.
- If left to float freely on the surface, the plant will naturally grow white roots that reach downward toward the substrate to anchor itself.
- Keep water movement calm and gentle, as heavy turbulence or rapid filter currents can disrupt leaf growth and stem stability.
- Prune surface leaves occasionally with sharp aquascaping scissors to prevent the floating lily pads from completely blocking light to plants below.
- Propagate new plants by letting trimmed leaves float on the water surface until tiny roots and brand-new tubers begin to sprout.

Frequently Asked Questions
1. How do I properly plant my Banana Plant into the substrate without killing the tubers?
Never fully bury the green "banana" tubers under your soil or gravel, as burying them completely will cause them to rot. Simply set the plant on top of the substrate or press the tubers no deeper than a quarter-inch into the top layer. The plant will naturally send down long, white anchoring roots into the substrate on its own.
2. Can I propagate new Banana Plants from leaf trimmings?
Yes, propagating Banana Plants is surprisingly easy. When you trim off long stems or surface leaves to keep the canopy under control, allow those cut leaves to float freely on the water surface. Over time, adventitious roots and miniature green tubers will sprout directly from the leaf base, giving you brand-new plants.
3. Why is my Banana Plant sending up long stems with pads to the surface?
This is a natural growth habit of Nymphoides aquatica as it seeks light. It sends pad-like leaves straight up to the surface to capture carbon dioxide and light, acting just like a miniature lily pad. If you prefer a shorter, bushier look near the substrate, simply trim those long surface-bound stems at the base.
