Eriocaulon sp. "Vietnam" is not yet known for a long time in Europe, however it has already proved to be an easy aquarium plant - in contrast to a number of other Eriocaulon rarities in the aquarium hobby. This plant, not yet determined to species, was originally found in the Vietnamese province Thanh Hoa. It is a medium-sized, about 15-30 cm tall Eriocaulon with relatively broad, medium-green, arching leaves, resembling Eriocaulon sp. "Goias".

This grass-like plant still grows with medium lighting and is even said to be suitable for hard water. However, a nutrient-rich substrate and a not too low CO2 concentration in the water column (at least 20 mg/l) are surely very conducive for its growth. With time, this plant forms a dense "grass tussock" with a number of leaf rosettes and can be divided into several single plants for propagation.
