Nymphoides aquatica

Species description

Care, breeding and tankmates

Plant profile

Placement

Foreground

It is best placed in the foreground or midground where its unique banana-shaped tubers can be clearly seen. It shouldn't be crowded by other plants. Allowing some space ensures it remains a focal point.

Botanical form

Rosette

Characterized by its cluster of thick, green, banana-like tubers at the base. It produces rounded, bright green leaves on long, slender stems. The tubers serve to store nutrients.

Growth

Slow

The growth rate is moderate. It will grow faster once it establishes a root system in the substrate. In high light, it may rapidly send lily-like leaves to the surface.

Substrate

High

Column fertilization

Recommended

Liquid fertilization is very beneficial, especially before the plant develops true roots. Macronutrients and micronutrients should be dosed regularly to keep the leaves green. It is quite sensitive to potassium deficiencies.

Root fertilization

Required

While not strictly necessary when first introduced, root tabs become beneficial once true roots grow down from the tubers into the substrate. A rich substrate will encourage larger, more robust growth.

Trimming

Occasional

Trim older, decaying leaves at the base to keep the plant looking tidy. If it sends too many leaves to the surface, snip them off to encourage lower, submerged growth. Pruning helps redirect energy to the main plant body.

Propagation

Division

Propagation can occur when the plant naturally splits or produces adventitious plantlets on older floating leaves. The rhizome can also be carefully divided. Ensure each division has some healthy tubers and leaves attached.

Sensitivity

Moderate

The 'bananas' should never be fully buried in the substrate, as this will cause them to rot. Simply rest them on the surface or gently press them slightly into the gravel or soil. It prefers cooler to moderate water temperatures.

Layout role

Foreground, Midground, accent, group

It acts as a unique, quirky novelty plant in the aquascape. Its structural form provides a great conversation piece. It breaks up traditional carpeting or stem plant layouts.
