Species description

Care, breeding and tankmates

Plant profile

Placement

Background

Its long, flowing, strap-like leaves make it a perfect background plant, especially in areas with moderate to high water movement. It looks exceptionally graceful as the leaves sway in the current. Because the leaves tend to stay narrow, it does not shade surrounding plants as heavily as other large Echinodorus.

Botanical form

Rosette

It forms a tight rosette producing numerous long, narrow, ribbon-like leaves that are somewhat translucent. Depending on the variant and lighting, the leaves can be bright apple green to dark brownish-red. The leaves tend to arch elegantly, adding a sweeping sense of motion to the aquascape.

Growth

Medium

It has a relatively slow to moderate growth rate, taking time to establish and reach its full, impressive size. Adding CO2 and strong lighting can increase the growth rate slightly, but it remains a steady, deliberate grower. This slow growth makes it very easy to manage without frequent pruning.

Substrate

High

A mature, nutrient-rich substrate provides the best environment for its strong root system. It thrives in aquasoils or fine gravel enriched with root tabs. A deep substrate is necessary as the roots will spread extensively over time, securely anchoring the plant in strong flow.

Column fertilization

Recommended

Liquid fertilization is beneficial for providing the readily available trace elements that maintain the leaves' translucent beauty. A light, regular dose of a comprehensive liquid fertilizer ensures the foliage remains unblemished. It absorbs nutrients well from the water column due to the thinness of its leaves.

Root fertilization

None

Like all swords, it greatly benefits from targeted root fertilization. Placing root tabs around the base every three to four months ensures it has access to essential macronutrients. This promotes the growth of more numerous, longer, and healthier leaves over its lifespan.

Trimming

Occasional

Trimming should consist of removing the oldest, outermost leaves as they begin to yellow or gather algae. Always cut these leaves as close to the crown as possible to maintain a clean rosette. It generally requires very little maintenance compared to fast-growing stem plants.

Propagation

Cuttings

It reproduces by developing inflorescences that carry small adventitious plantlets. However, it tends to produce runners less frequently than other common sword plants. When runners do appear and plantlets develop roots, they can be carefully snipped off and replanted.

Sensitivity

Moderate

It is a robust plant that can adapt to a wide range of water parameters, though it often appreciates slightly cooler water. It is not particularly sensitive, but its long leaves can become a site for algae growth if flow is poor. Herbivorous fish usually leave it alone.

Layout role

Background

It provides a highly graceful, sweeping aesthetic that softens the hard edges of rocks or driftwood in the background. The ribbon-like leaves create a wonderful sense of flow and movement in the aquarium. It serves as an excellent backdrop for smaller, contrasting midground species.
