TCulture Hygrophila angustifolia rubra
This decorative, undemanding Hygrophila is labeled by aquarium plant nurseries as H. corymbosa "Stricta", mistakenly also "Hygrophila guanensis" or "H. guyanensis". It resembles Hygrophila corymbosa "Siamensis" but differs by more red brown coloration, especially under intense lighting.
Hygrophila corymbosa "Stricta" manages with medium lighting and hard water, however a good nutrient supply is beneficial. Especially potassium deficiency leads to perforated older leaves in Hygrophilas. This stem plant is easily propagated by cuttings.
With its upright, strong stems and large leaves, this Hygrophila looks best as a group in the midground to background of larger tanks. It is also suited for "plant streets" in Dutch style aquariums. It can also be used as a half-emersed plant in open tanks where its nice purple flowers can be expected.
