Eriocaulon cinereum is a delicate, rare aquatic grass from Southeast Asia producing a compact rosette of fine, hair-like leaves with an intricate star-shaped form. It is a collector's plant, sought after by experienced aquascapers for the unique fine texture and soft, naturalistic quality it brings to high-tech planted layouts.
It is a demanding species requiring consistently bright light and CO2 injection. Soft, slightly acidic water is preferred, and the plant is sensitive to nutrient imbalances and unstable conditions. It is not suited to low-tech aquariums and is best kept by hobbyists with experience in high-tech planted systems.
Supplied as an established potted plant, Eriocaulon cinereum suits well-maintained aquariums from 50 litres upward equipped with CO2 and bright lighting. Placed in the foreground or midground, it rewards careful attention to water chemistry and stable parameters with slow but beautiful, structured growth.
