Hygrophila corymbosa 'Stricta' - Plant

Hygrophila corymbosa ‘Stricta’ is a hardy stem plant with upright stems and long, pointed, light green leaves. It grows quickly and creates a substantial green backdrop, making it particularly useful in medium to large aquariums. Stems can reach around 40–50 cm if left untrimmed, so allow plenty of space for the plant to develop.

Compared with Hygrophila corymbosa ‘Compact’, ‘Stricta’ develops a taller, more open shape and needs more room. Its larger leaves provide a clear contrast against fine-leaved Rotala varieties, while the fresh green colour works well beside red stems. In open aquariums, shoots can grow above the surface and may produce small flowers.

Moderate lighting and regular feeding suit it well, and it adapts to both soft and hard water. CO₂ injection is optional but encourages faster growth and helps maintain fuller stems. Dose a complete aquarium fertiliser consistently and provide nutrients at the roots, as its rapid growth creates a steady nutrient demand. Trim regularly to encourage side shoots and prevent the upper canopy from shading lower leaves.

Plant individual stems directly into the substrate, leaving some space between each stem for light and water circulation. Low to moderate lighting is sufficient, although stronger lighting encourages denser and more compact growth. CO₂ injection is not required but will increase growth rate and overall vigour. Provide regular liquid fertilisation to support its relatively fast growth.

Trim taller stems periodically to encourage branching and maintain a bushier shape. Healthy trimmed tops can be replanted to expand the group.
