Hygrophila corymbosa ‘Siamensis 53B’

🌿 Hygrophila corymbosa ‘Siamensis 53B’

Hygrophila corymbosa ‘Siamensis 53B’ is a striking stem plant known for its long, narrow leaves and attractive reddish to bronze coloration under stronger lighting. It is a beautiful variation of the classic Siamensis type and can add both height and warm color to a planted aquarium.

🌱 Growth & Appearance

This variety develops upright stems with elongated, relatively narrow leaves that form a dense and elegant appearance as the plant matures. Under stronger light and good nutrition, the newer leaves can develop deeper bronze, reddish or copper tones, creating an attractive contrast against green plants.

It is a vigorous grower once established and can gradually form a substantial group. Regular trimming encourages branching and allows the plant to become fuller rather than producing only tall vertical stems.

💡 Lighting & CO₂

Hygrophila corymbosa ‘Siamensis 53B’ is adaptable and can be grown in low-tech aquariums, although stronger lighting and CO₂ will generally produce more compact growth and stronger coloration.

For the best reddish or bronze tones, provide good lighting along with consistent nutrient availability. CO₂ is not strictly required, but it can significantly improve growth and overall appearance.

🪴 Planting & Maintenance

Plant individual stems into the substrate with enough space between them to allow light and water circulation. As the plant grows, trim the upper portions and replant healthy cuttings to create a denser group.

It is a relatively fast and vigorous plant, so regular trimming may be needed to maintain the desired height and prevent it from shading smaller plants.

🌿 Best Use

Hygrophila corymbosa ‘Siamensis 53B’ works especially well as a midground to background stem plant in natural-style, Dutch-style and jungle-style aquascapes.

Its long leaves and potential bronze-red coloration provide excellent contrast against fine-leaved green plants and can be used to create a strong visual transition between different plant groups.
