01

Overview

This Amazon-basin milfoil dresses its stems in soft, whorled plumes that stay fresh light-green rather than going scraggly like the temperate species. It grows centimeters per day when fed, making it equal parts ornament and nutrient export.

Aquascaping use

Use its feathering to dissolve hard background lines and give small fish drifting cover. In Dutch-style tanks it makes a classic fine-texture street.

Planting

Plant cuttings loosely; nodes root fast wherever they touch. Leave working space around each stem for the plume diameter.

Substrate note

Flexible

04

Light & CO₂

Medium light keeps whorls tight; CO₂ pushes already brisk growth to weedlike. Insufficient light stretches the internodes visibly.
