Hygrophila multiforme
Hygrophila multiforme is the collective name for a whole group of closely related species from tropical and subtropical Asia, united under the scientific name Hygrophila salicifolia. This group is taxonomically very complex. Some scientists divide it into separate species, such as Hygrophila angustifolia, Hygrophila Araguaia. Others consider it one species, but with several varieties, for example, it is indicated in the Flora of China publication. In addition, this name is often erroneously indicated in relation to Hygrophila corymbose.
Despite the difference in points of view, Hygrophila diverse (even if they are different species), several typical features can be distinguished: an upright stem with long (10–15 cm) leaf blades 2–3 cm wide. Under conditions of high light and iron-rich soil, underwater leaves acquire reddish-brown color. When growing above water, pale purple flowers form in the axils of the leaves.
Undemanding and easy to grow plant. Able to grow successfully in moist substrates, such as paludariums, and completely submerged in water. Prefers soft nutrient soil, warm water. The values of hydrochemical parameters are not significant. In favorable conditions, rapid growth is observed, which can be restrained by pruning, which in turn will give volume to the bush due to the appearance of new shoots at the cut point.
