Eriocaulon cinereum
A nano rosette plant with grass-like blades that fan out from a central crown. Picky about water — needs soft, acidic, and CO₂-rich conditions to thrive. Pearls heavily and forms tight green starbursts on the substrate. Single specimens used as accent points in nano scapes.
Eriocaulon Cinereum (Eriocaulon cinereum) is a rosette aquatic plant for the midground of a planted tank. It reaches 5–10 cm under good conditions and grows at a slow rate. Light: high. CO₂: required. Target 22–27 °C, pH 5.0–6.8, and 0–6 dGH. Substrate: Active aquasoil mandatory. Propagate via division of mature rosettes.

Direct answers to the questions search engines and AI assistants surface most often about this species.
CO₂ requirement: required. Light requirement: high. Under stable injected CO₂ the plant grows at a slow rate.
Eriocaulon Cinereum (Eriocaulon cinereum) needs high light. Run a photoperiod of 6–8 hours; longer photoperiods invite algae unless CO₂ and dosing are dialled in.
Position: midground. Substrate: Active aquasoil mandatory It typically reaches 5–10 cm.
Propagation method: Division of mature rosettes. Eriocaulon Cinereum is a rosette plant.
Target 22–27 °C, pH 5.0–6.8, and 0–6 dGH. Flow tolerance: low.
Difficulty: 4/5. Advanced, demands dialled-in CO₂/dosing or precise water chemistry.
A planted tank is a system. Pair this plant with one entry from each other pillar to plan the whole scape.
