Description de l'espèce
Geographical Origin and Habitat: Native to the tropical regions of Central and South America, where it grows as an emergent or submersed plant along the margins of slow-flowing rivers, marshes, and ponds with calm, nutrient-rich waters.
Taxonomy & Genetics: Belongs to the family Onagraceae, genus Ludwigia. The species exhibits high phenotypic plasticity based on lighting and nutrient levels, with famous varieties such as L. inclinata var. verticillata ("Cuba" or "Pantanal").
Physical Structure: An upright stem plant with alternate or whorled leaves depending on the variety. Under high light, the nodes shorten and the leaves become dense, fine, and needle-like in some varieties.
Color & Texture: Displays a spectacular color spectrum ranging from pale green and yellow under moderate light, to fiery red, orange, and vivid pink under high-intensity lighting and optimized nutrient dosing.
Soins, reproduction et cohabitation
Lighting & CO2: Requires extremely high lighting (at least 50 lumens/liter or high PAR levels). CO2 injection must be high and stable (25-30 ppm) to prevent growth stunting and the loss of lower leaves.
Nutrition & Substrate: Needs a rich, fertile substrate containing high levels of iron and micronutrients. Demands regular water column dosing of macro (NPK) and microelements (especially iron to promote red coloration).
Water Chemistry: Strongly prefers very soft, acidic water (KH 1-4, GH 2-6, pH 5.5-6.5). High carbonate hardness inhibits growth and causes curly or deformed leaf tips.
Space Management & Placement: A fast-growing plant best placed in the midground or background of the aquarium. Ensure adequate spacing between individual stems so light can reach the lower leaves.
Pruning: Pruned by cutting the healthy top portion of the stem and replanting it. Remove the old bottom portion if it becomes woody or bare, as the replanted tops will quickly root.
Risks & Diseases: Highly sensitive to nutrient deficiencies. Iron deficiency causes pale, washed-out colors, while insufficient CO2 leads to melting leaves and stem decay.

Profil de plante
- Emplacement
- Arrière-plan
- Optimal placement for Ludwigia inclinata is as a background. Careful positioning allows it to receive adequate light and flow. This strategic placement ensures it does not overshadow smaller plants while exhibiting its best form.
- Forme botanique
- Tige
- Botanically, Ludwigia inclinata is characterized as a stem plant. Its unique physiological traits make it a fascinating addition to the ecosystem. The leaf structure and overall form adapt closely to its submerged environment.
- Croissance
- Rapide
- The growth rate of Ludwigia inclinata is generally considered very fast. This steady development necessitates a well-planned maintenance schedule. Adjusting environmental factors can slightly speed up or slow down this rate.
- Substrat
- Moyen
- Ludwigia inclinata develops best in a fertile, nutrient-dense substrate like aquasoil, which supplies the essential iron and trace elements needed for its rapid growth and orange-red pigmentation. The plant forms an extensive and hungry root system that requires a substrate depth of at least 5 centimeters for proper anchorage and nutrient uptake. While it can generate adventitious roots to feed from the water column, robust root feeding is critical to prevent the lower portions of the stems from rotting. A fine to medium-grained substrate allows its delicate roots to penetrate easily and establish a strong foundation.
- Fertilisation de la colonne d'eau
- Nécessaire
- For column fertilization, Ludwigia inclinata prefers a rich dosing regimen. Liquid fertilizers are efficiently absorbed through its submerged surfaces. Consistent daily or weekly dosing ensures steady nutrient availability.
- Fertilisation racinaire
- Facultative
- Regarding root fertilization, it is absolutely true that Ludwigia inclinata requires a nutrient-rich substrate. A quality aquasoil or root tabs can significantly boost its long-term health. The root system plays an active role in stabilizing the plant and absorbing minerals.
- Taille
- Occasionnelle
- Maintenance for Ludwigia inclinata primarily involves aggressive topping. Using sharp aquascaping scissors ensures clean cuts that heal quickly. Regular pruning encourages a more compact and aesthetically pleasing form.
- Propagation
- Boutures
- Propagation of Ludwigia inclinata is typically achieved through cuttings. This method is straightforward and yields a high success rate. Newly propagated sections should be planted with sufficient space to establish themselves.
- Sensibilité
- Sensible
- Ludwigia inclinata is particularly sensitive to hard water and low CO2. Sudden changes in water chemistry can trigger negative reactions or melting. Maintaining a stable environment is the best preventative measure against these issues.
- Rôle dans le décor
- Arrière-plan
- In an aquascape, Ludwigia inclinata serves excellently as a tall colorful background. Its visual characteristics draw the eye and create depth within the layout. It pairs well with contrasting textures to enhance the overall composition.
