Hygrophila corymbosa ‘Siamensis’

Description

This large stem plant from Thailand is popular for a long time due to its frugality. In contrast to “normal” broadleaf Hygrophila corymbosa, its submerged leaves are lanceolate. They may reach a length of about 16 cm and a with of about 3,5 cm, with coarsely wavy edges. The upper side is light to medium green, the underside greyish green. Strong lighting may lead to slightly bronze tones. Well developed shoots are up to 25 cm wide. The strong, about 3 to 5 mm thick stem grows upright and is densely set with leaves. The emersed plant has blueish green leaves and ramified inflorescences with little purple flowers in the leaf axils.

Hygrophila corymbosa “Siamensis” is content with medium lighting and tolerates hard water, however it benefits from good macro- and micronutrient supply, also via the substrate. CO₂ addition is not necessary but improves greatly its growth. Due to its fast growth, regular trimming is necessary when emersed growth is not wanted. The plant is easily propagated by cuttings.

This amphibious plant from Thailand looks especially well in large aquariums, as a stand in the midground to background. As an undemanding, fast growing plant, it is recommended for beginners and newly set up tanks. It fits well in Dutch style planted tanks and Asia-themed biotope aquariums. It is also interesting as emersed, flowering plant in open tanks, paludariums and Wabi-Kusa.
