Potamogeton perfoliatus

Species description

Care, breeding and tankmates

Plant profile

Placement

Background

Best placed in the background due to its size and rapid vertical growth. It can also look spectacular as a standalone focal point in larger tanks. Needs plenty of space to spread out.

Botanical form

Stem

A distinctive stem plant characterized by round, perfoliate leaves that clasp and completely encircle the stem. It ranges in color from bright, vibrant green to reddish-brown under strong light.

Growth

very-fast

Fast-growing, often reaching the water surface within a matter of weeks. It requires frequent trimming to maintain its shape and prevent it from shading the entire tank. CO2 significantly boosts its speed.

Substrate

High

Column fertilization

Recommended

Regular dosing of comprehensive liquid fertilizers is highly recommended. High CO2 and robust macro dosing enhance the overall leaf size and growth rate. Iron supplements boost any reddish hues.

Root fertilization

Required

A nutrient-rich aquasoil or the addition of root tabs will significantly improve overall health. Strong roots help anchor its thick stems securely. Substrate feeding is key for thicker foliage.

Trimming

Regular

Prune by topping; remove the upper portion of the stem. The remaining lower part will sprout new shoots from the nodes. Replant the tops if you wish to multiply the stand.

Propagation

Cuttings

Propagates very easily by cuttings. Replant the cut stems directly into the substrate. The cuttings usually take root within a few days.

Sensitivity

Moderate

Can melt if water parameters swing drastically or if relocated abruptly. Requires good water circulation to prevent debris buildup on its broad leaves. Susceptible to spot algae under poor flow.

Layout role

Background

Creates a striking textural contrast with its unique round, clasping leaves. Ideal for creating dense, eye-catching background thickets. Draws the eye due to its unusual morphology.
