A perennial freshwater aquatic plant that grown completely submerged. The stems grow to 2 metres or more and are floating with roots at the lower nodes and narrow, undivided leaves in whorls of 3 to 8 at each node. White flowers are attached to long thread-like stems and float on surface of water but do not form seed in Australia.

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.
