Hygrophila balsamica is a large strong stem plant with finely feathered light green leaves. It is especially beautiful as a group planting in the middle ground of large tanks. Lots of light and CO2 as well as a good supply of iron are recommendable so it keeps it beautiful light green hue and sprouts large, finely feathered leaves.
The bog plant Hygrophila balsamica is native to India and Sri Lanka. In aquaristics it has long been known but is only rarely used for aquarium decoration, as it is poisonous to fish and inverts if its emersed shoots are directly planted in the aquarium.
As soon as it has assumed its submersed form it ceases to be noxious, though, and can be used in a stocked tank without causing problems. Most aquatic plant nurseries cultivate their plants emersed, however, and thus it is easily understandable why this plant is so rare in the hobby. Nowdays common H. balsamica clones from nurseries like Anubias can be used emerged in a tank without problems.
