Species description

Care, breeding and tankmates

Plant profile

Placement

Background

Due to its enormous potential size, it is strictly a background plant for very large aquariums. It can easily dominate a tank and heavily shade out underlying carpet plants. It can also be successfully grown emergent in open-top tanks or paludariums.

Botanical form

Rosette

It forms a towering, massive rosette with extremely large, broadly ovate to heart-shaped leaves. The stems are very long, thick, and incredibly robust. It develops a massive, highly invasive root system to support its sheer physical size.

Growth

Medium

The growth rate is exceptionally fast, especially when provided with strong light and abundant nutrients. It rapidly produces extremely large, sweeping leaves that reach the surface. It will quickly outgrow small to medium-sized aquatic setups.

Substrate

High

As a large and robust species, the Floribundus Sword requires a deeply layered, nutrient-rich substrate to accommodate its massive root structure. It draws the majority of its sustenance directly from the bottom, so providing an aqua soil or clay-based substrate of 3 inches (7.5 cm) or deeper is highly beneficial. Without a fertile bed or regular addition of root tabs, its growth will be stunted and its large leaves may show signs of nutrient deficiency.

Column fertilization

Optional

While root feeding is its primary mechanism, its massive biomass requires supplemental column fertilization. Dosing potassium, iron, and trace elements helps maintain the enormous leaves in pristine condition. Without this column support, the older foliage may quickly degrade and melt.

Root fertilization

Required

It is an extremely aggressive root feeder that constantly searches for nutrients. Frequently replenishing root tabs deep around its massive base is necessary for sustained health. A deep layer of nutrient-rich substrate is vital to accommodate its extensive root network.

Trimming

Occasional

Aggressive pruning is frequently needed to prevent the plant from entirely taking over the aquarium. Remove the largest, oldest outer leaves to carefully manage its footprint and prevent shading. Trim the thick leaves as close to the crown as physically possible.

Propagation

Runners

It propagates by sending out very large, thick flower stalks that develop numerous tiny plantlets. These plantlets can be easily harvested once they form their own white roots. It may also occasionally split naturally at the central crown.

Sensitivity

Moderate

It is an incredibly hardy and robust plant that can survive tough conditions. Its main sensitivity is severe nutrient starvation due to its immense appetite. It can easily adapt to a wide variety of water parameters but strongly prefers stable conditions.

Layout role

Background

This plant is the ultimate background giant for massive, large-scale aquascapes. It provides significant structural volume and creates a wild, immersive jungle-like aesthetic. It is absolutely perfect for large South American river biotope aquariums.
