Ludwigia inclinata var. verticillata "Pantanal"

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

It is best utilized as an accent plant in the midground or background, where its striking color can break up green monotony. Because of its intense coloration, placing it alongside light green plants enhances its visual impact. Avoid placing it in the shadows, as it requires unobstructed access to intense light.

Botanical form

Stem

This stunning variety features very fine, needle-like leaves arranged in a tight whorl around a central stem. The submerged form is famously known for its brilliant pinkish-red to magenta crown, which is larger and more colorful than the 'Cuba' variant. Its emersed form is unassuming, with simple green, oval leaves.

Growth

Fast

When its exact environmental demands are met, it grows incredibly fast, shooting straight up toward the light source. This rapid vertical growth necessitates frequent topping to prevent it from outgrowing the aquarium. However, if conditions dip even slightly, its growth will stall immediately.

Substrate

High

This highly demanding species requires a premium, nutrient-packed aqua soil to sustain its rapid growth and vivid coloration. The root system is delicate but expansive, necessitating a fine-grained substrate layer of at least 2-3 inches to prevent uprooting. To achieve its full potential, the substrate must be consistently enriched with iron and trace elements.

Column fertilization

Recommended

Aggressive liquid fertilization is required, especially daily dosing of iron and micronutrients. It also consumes high amounts of macronutrients (NPK) due to its rapid metabolism. Any deficiency in the water column will quickly lead to pale, stunted new growth and eventual necrosis of the stem.

Root fertilization

None

While water column dosing is critical, a nutrient-rich aquasoil substrate is highly recommended to support its demanding nature. Root tabs can be beneficial for providing a constant source of iron directly to the root zone. A healthy root system ensures the plant remains anchored and robust as it grows rapidly upwards.

Trimming

Occasional

Trimming should be done by carefully cutting the brightly colored tops and replanting them to maintain the healthiest specimens. The remaining bottom portions often struggle to produce new shoots and are frequently discarded by aquascapers. Regular maintenance is required to keep a group looking neat and to prevent shading of neighboring plants.

Propagation

Cuttings

Propagation is straightforward through top cuttings. Snipping a healthy, brightly colored top and pushing it gently into the substrate will yield a new plant. To ensure the cutting takes hold, verify that both lighting and CO2 are at peak levels during the replanting phase.

Sensitivity

Moderate

It is notoriously intolerant of hard water, low CO2, or inadequate lighting, melting away quickly under suboptimal conditions. It will immediately show signs of stress, such as greening of the crown or twisting of new leaves, if nutrients fluctuate. It is also sensitive to certain algaecides and chemical treatments.

Layout role

Midground, accent, Background

The 'Pantanal' variant serves as a premier, high-impact focal point in advanced planted aquariums. Its dazzling pink-magenta starburst tops draw the eye instantly. It is typically used in small, meticulously maintained groups to showcase the aquascaper's skill and dedication.
