越南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".

这种草状植物在中等光照下仍能生长，甚至据说适合硬水。然而，营养丰富的基质和不太低的CO_2.水柱中的浓度（至少20毫克/升）肯定非常有利于其生长。随着时间的推移，这种植物形成了一个密集的“草丛”与一些叶莲座丛，并可分为几个单一的植物繁殖。

越南can be used in aquascaping similarly to Blyxa japonica - e.g. as a meadow-like stand in the midground, linking the background with low groundcovers in the foreground, or as scattered tufts between hardscape elements. In contrast to similar rosette plants such as Sagittaria subulata or Helanthium bolivianum, it does not develop runners, making its handling easy. This undemanding Eriocaulon surely deserves a wide distribution in the aquarium hobby.
