Rotala sp. 'Vietnam' is a fine-leaved, beautifully coloured stem plant. It is similar to Rotala wallichii; possibly it is also a form of this species. The stem is dark red like Rotala sp. 'Cambodia'. R. sp. 'Vietnam' differs from the latter two plants by having somewhat longer leaves, up to about 2.5 cm long. These have a lighter shade than in R. sp. 'Cambodia'. It prefers about the same culture conditions as Rotala wallichii; rather strong lighting, soft water, CO2 supply and regular fertilization with macro- and micronutrients are recommended for healthy growth.
