Ludwigia inclinata var. verticillata 'Curly'

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

This plant should be positioned in the midground or background where its curly, textured foliage can be properly showcased. It forms a dramatic, eye-catching centerpiece when planted in a small, dense group. Care must be taken not to place it where taller plants might shade it.

Botanical form

Stem

The 'Curly' variant is distinguished by its fascinating, spiraling leaves that twist tightly around the main stem. These leaves can exhibit colors ranging from light green to a vivid orange-red under strong illumination. The stems themselves are somewhat delicate but grow strictly upright.

Growth

Fast

Its growth rate is relatively fast when all of its demanding requirements are met, though it may grow slightly slower than the 'Cuba' variant. Under ideal conditions, it rapidly produces vertical shoots that will eventually breach the surface. If environmental conditions are less than perfect, its growth will stall significantly.

Substrate

High

Thrives best in a nutrient-rich aqua soil that offers a constant supply of essential macro and micronutrients. Its extensive root network requires a deep, soft substrate layer of around 2-3 inches to spread and anchor properly. Regular fertilization of the substrate is critical to maintain the plant's unique curly leaves and prevent stunted growth.

Column fertilization

Recommended

Water column dosing is critical for maintaining the vibrant colors and structural integrity of its curling leaves. Consistent daily dosing of a comprehensive liquid fertilizer, particularly rich in iron, is highly recommended. Deficiencies in the water column will quickly manifest as pale or decaying foliage.

Root fertilization

None

While it draws heavily from the water column, it benefits greatly from being rooted in a rich, active soil. Providing nutrient-dense root tabs will give the plant additional reserves to draw upon during periods of rapid growth. A nutrient-rich substrate also aids in the swift establishment of cuttings.

Trimming

Occasional

Trimming should be done carefully by cutting the top portions and replanting them into the substrate to maintain a neat appearance. The lower stems can be left in place, though they may take some time to develop new, healthy side shoots. Regular pruning is necessary to prevent the plant from becoming excessively tall and leggy.

Propagation

Cuttings

Propagation is easily achieved by taking cuttings from the top portion of healthy stems. Simply plant the cut tops directly into the substrate, where they will quickly develop new roots. The bottom portions of the stem will often branch out, creating a bushier appearance over time.

Sensitivity

Moderate

This plant is notoriously sensitive and acts as an indicator species for water quality and nutrient balance. Fluctuations in CO2 or insufficient lighting will cause its unique curled leaves to straighten out or melt away completely. It is also prone to stunting if there is a sudden drop in micronutrients.

Layout role

Midground, Background

It acts as a unique textural focal point in advanced aquascapes due to its bizarre, spiraling leaf structure. It contrasts exceptionally well against plants with flat, broad leaves or dark green coloration. It is best used sparingly as a rare, jewel-like accent rather than a mass background filler.
