Species description

Care, breeding and tankmates

Plant profile

Placement

Midground

It is ideally placed in the midground or background depending on tank size. Grouping several stems together creates an attractive, dense thicket. Its perfectly round leaves offer a very tidy and uniform appearance in the aquascape.

Botanical form

Stem

As the name implies, it features noticeably rounder leaves compared to the standard species. The leaves are light green, fleshy, and grow opposite each other on a thick, upright stem. The highly symmetrical growth pattern is visually very soothing.

Growth

Medium

This variant grows at a moderate pace, making it very easy to manage. It does not aggressively take over the aquarium, requiring only occasional pruning. Its predictable growth makes it a favorite for structured layouts.

Substrate

Medium

The "Rundblättrig" (round-leaved) variant of Bacopa monnieri thrives best when planted in a highly nutritious substrate, heavily relying on root absorption to fuel its broader leaf development. Its vigorous roots require a deep, active aqua soil bed of about 5 to 7 centimeters to anchor properly and access the rich mineral reserves needed for optimal health. A fine-textured substrate allows the delicate root hairs to penetrate easily, ensuring the thick stems are structurally supported and well-fed. Without a nutrient-dense base, this demanding cultivar may struggle to maintain its distinct round leaf shape and vibrant green coloration.

Column fertilization

Recommended

Liquid fertilization is effective as it absorbs nutrients directly from the water column. Regular additions of trace elements keep the foliage a vibrant, healthy green. Adequate potassium helps maintain the integrity of its beautiful round leaves.

Root fertilization

Recommended

A nutrient-rich substrate is beneficial and promotes a strong root system. While it can draw most of its needs from the water, root tabs provide a reliable backup source. Good root anchorage is essential as the stems grow taller and thicker.

Trimming

Regular

Prune by simply cutting the top portions of the stem with sharp scissors. The lower parts will shoot new side branches from the nodes. Replanting the trimmed tops quickly thickens the plant cluster.

Propagation

Cuttings

Propagation is incredibly easy through stem cuttings. Snip any healthy stem section and insert it straight into the substrate. It will grow new roots in just a few days.

Sensitivity

LOW

It retains the extreme hardiness of the wild Bacopa monnieri species. It handles fluctuations in water parameters very well and is rarely affected by common pests. It is highly resilient against melting or sudden die-offs.

Layout role

Nano, Midground, Background

Its round leaves provide a wonderful geometric contrast to grassy or needle-like plants. It is excellent for softening the sharp lines of rocks and wood. It serves as a beautiful, structural accent in any nature aquarium or Dutch-style setup.
