Eriocaulon sp. Vietnam - Rare Freshwater Aquarium Plant

Eriocaulon sp. Vietnam is a rare and striking freshwater aquarium plant featuring broad, medium-green arching leaves that form a beautiful rosette shape. Originating from Thanh Hoa, Vietnam, this intermediate-level plant is prized by aquascapers for its dramatic visual impact and unique form. While it requires a nutrient-rich substrate and moderate CO2, the reward is one of the most photogenic plants in the hobby.

• Lighting: Medium to High — needs good lighting to thrive
• CO2: Recommended — performs best with CO2 injection
• Substrate: Nutrient-rich aquasoil preferred; slightly acidic substrate ideal
• Temperature: 68–82°F (20–28°C)
• pH: 5.5–7.0 (soft, slightly acidic water preferred)
• Growth Rate: Slow to Moderate
• Placement: Midground — stunning as a focal point
• Propagation: Division — separate offshoots as the rosette expands

Does it need CO2?
CO2 is strongly recommended. While Eriocaulon Vietnam can survive without CO2 under strong lighting, it will not thrive or reach its full potential.

What substrate works best?
Nutrient-rich aquasoil is ideal. Inert substrates require root tabs to support this heavy root feeder.

How do I plant it?
Remove from the pot, carefully separate the rock wool from the roots, and bury just the roots in the substrate — leaving the crown exposed.

Live plants ship via USPS Priority. Plants are wrapped in damp paper towels and sealed in bags to maintain moisture during transit.

Note: Some plants may experience minor melting after being introduced to a new tank. This is normal — new growth will appear within 1–2 weeks.
