Lindernia grandiflora

Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

Given its visual impact, it is ideally placed in the midground or background of the aquarium. It creates a stunning focal point when planted in small, dense clusters. In shallow tanks, it can even be allowed to grow emerged, where it may produce small flowers.

Botanical form

Stem

This species is distinguished by its larger, rounded to ovate leaves compared to other Lindernia species. The leaves grow oppositely along sturdy stems, displaying a striking bright green hue. Its overall form is upright, but it can bush out significantly when trimmed.

Growth

Medium

It grows at a moderate to fast pace when provided with strong light and CO2 supplementation. Consistent nutrient levels encourage rapid vertical growth and lateral branching. Under lower light, its growth slows down, and the internodes may become elongated.

Substrate

High

Lindernia grandiflora is a demanding plant that thrives strictly in nutrient-rich, active aquatic soils capable of fueling its robust metabolic rate. The plant rapidly develops a strong, deep root structure that relies on the substrate for a constant intake of nitrogen, phosphorus, and trace minerals. A generous substrate depth of 2.5 to 4 inches is highly recommended to accommodate its vigorous root expansion and provide long-term stability. Without a high-quality, fertilised base, this species may struggle to produce its characteristic broad leaves and sprawling growth.

Column fertilization

Recommended

Column fertilization is crucial as the plant rapidly absorbs nutrients through its large leaf surfaces. A balanced liquid fertilizer containing nitrogen, phosphorus, and potassium should be dosed regularly. Maintaining optimal nutrient levels prevents premature deterioration of the lower foliage.

Root fertilization

Recommended

A nutrient-dense substrate provides a significant advantage for Lindernia grandiflora. Utilizing aquasoil or placing root tabs near the base ensures a strong, healthy root network. Robust roots lead to thicker stems and larger, more resilient leaves.

Trimming

Occasional

Frequent pruning is beneficial to keep its size in check and encourage a bushy, compact form. Trimming the tops forces the plant to send out multiple side shoots. Replanting the cuttings is an easy way to multiply the plant and thicken the cluster.

Propagation

Cuttings

Like most stem plants, propagation is effortlessly done by cutting the stem and replanting the top. The replanted cutting will quickly root, and the original stem will grow new shoots. Ensure each cutting has a few nodes to facilitate successful rooting.

Sensitivity

Moderate

It can be sensitive to poor water circulation and shading from taller plants. Ensure it receives unobstructed light to prevent the lower portions from decaying. Sudden shifts in water quality or temperature can cause temporary growth stunting.

Layout role

Midground, Nano, Background

Its bold leaf texture makes it an excellent contrasting plant against fine-leaved species. It serves well as a midground accent or a background filler in smaller aquascapes. Its bright green color adds a refreshing vibrancy to any planted layout.
