About
Eriocaulon aquaticum is a rosette-forming aquatic plant in the family Eriocaulaceae, native to nutrient-poor lakes in North America and Europe. Slender linear leaves radiate outward, and established clumps take on a distinctive pineapple-like form. It is one of the more challenging pipeworts to grow, requiring strong lighting, CO2 injection, abundant substrate nutrients, and clean soft water. Because it favors nutrient uptake through the roots, a nutrient-rich soil substrate suits it. Being sensitive to environmental change and poor water quality and prone to melting, it demands stable management and is suited to advanced hobbyists. It can be propagated by dividing the daughter plants it produces. Scattered in the midground, it has a striking presence. It prefers soft, slightly acidic water.
