Plant profile

Placement

Midground

This plant is best suited for the midground or background, depending on the frequency of trimming. Because of its tendency to grow rapidly towards the light, it is excellent for creating dense, bushy thickets. It has a slightly sprawling habit, so it needs adequate lateral space to prevent it from tangling with smaller foreground plants.

Botanical form

Stem

It features opposite, rounded to slightly mint-like leaves arranged along a somewhat delicate, square-shaped stem. The leaves are a bright, cheerful light green, emitting a distinct, pleasant minty fragrance when crushed or trimmed. When allowed to grow emerged, it will produce tiny, attractive white or pale purple flowers.

Growth

Fast

Clinopodium brownei exhibits a fast to very fast growth rate when provided with intense lighting and CO2 injection. Under these conditions, it requires weekly pruning to maintain a desirable shape and prevent it from reaching the surface and blocking light. In low-tech tanks without CO2, its growth is more manageable, though the internodes will be wider.

Substrate

Medium

It prefers a nutrient-rich, soft substrate such as aquasoil, where its fine roots can spread easily. While it can survive in plain sand or fine gravel, its growth will be significantly stunted unless the substrate is aggressively supplemented with root fertilizers. A soft substrate also makes it much easier to replant delicate cuttings during propagation.

Column fertilization

Recommended

Liquid fertilization is highly recommended, as the plant readily absorbs nutrients through its leaves to support its rapid vertical growth. A steady supply of water column nutrients ensures that the lower leaves remain healthy and do not drop off due to starvation. Regular dosing of an all-in-one fertilizer will keep the entire thicket lush.

Root fertilization

None

Root feeding is highly beneficial and encourages the plant to establish a strong, anchoring root system. Placing nutrient-rich root tabs at the base of the stems provides a reliable backup source of essential elements, particularly iron and phosphorus. This ensures the plant remains vigorous even if water column dosing is occasionally forgotten.

Trimming

Occasional

Due to its fast growth, frequent trimming is necessary to maintain its shape and prevent it from shading out other plants. To create a bushy appearance, simply top the stems and replant the cuttings; the original stems will produce multiple side shoots. Regular pruning also prevents the lower portions of the stems from becoming bare due to lack of light.

Propagation

Cuttings

Propagation is extremely straightforward through standard stem cuttings. Simply cut the top portion of a healthy stem and push it gently into the substrate; it will develop new roots within a few days. The remaining bottom portion will quickly sprout multiple new side shoots, leading to a denser, bushier appearance.

Sensitivity

Moderate

This plant is relatively hardy and adaptable to a wide range of water parameters, though it prefers slightly acidic to neutral pH. It is sensitive to poor lighting, which will cause it to become leggy and drop its lower leaves. It transitions well between submersed and emersed states, making it very forgiving for aquascapers.

Layout role

Midground, Background

Clinopodium brownei is highly valued for its bright green color and delicate leaf shape, providing excellent contrast against broad-leaved plants or dark hardscape. It serves well as a midground bush when kept trimmed or as a background filler in taller tanks. In Wabi-Kusa or ripariums, its trailing nature adds a natural, wild aesthetic.
