A feathery leaved perennial aquatic plant with stems growing indefinitely but easily breaking into sections. The leaves are widly nspaced along the stem and consist of many slender segments arranged in a fan-shape. It remains completely submerged, with only the flowers protruding above the surface. These are less than 1 cm across with six white petals. 

This is a native, aquatic fern that prefers slow moving or still water. Fronds produce leaflets in the shape of four-leaf clovers and generally float on the water's surface. Attractive foliage and vigorous growth make Common Nardoo an excellent water feature.

A vigorous native perennial aquatic species with foxtail-like stems held above the water. Plants occur in shallow waters and provide shelter and spawning areas for fish. Thrives in full-sun to light-shade at a depth of 60 cm.
