Limnophila Vietnam. This beautiful stem plant grows small, narrow leaves that are tightly clustered in a star shape, and bright green in colour. Under intense lighting, Limnophila Vietnam will quickly creep along the substrate to form a dense carpeting effect, and may take on reddish-brown hues. In lower light conditions it will grow upright and can be used to create small bushes. Limnophila Vietnam is moderately easy to grow, requiring medium to high lighting and regular fertilisation with CO2 injection also recommended.
