Long grass-like leaves that sway in the current — the closest thing in the hobby to a stand of underwater reeds. One of the very few sedges that live fully submerged.

Appearance
Narrow green ribbon leaves 20–30 cm long grow from a rosette a hand's width across. The whole plant moves with the flow, which is the main reason it is planted.
Keeping
Moderate demands: it wants decent light and answers well to carbon dioxide; growth is slow, so pruning is rare. Water movement suits it — in a still tank the leaves collect dirt and algae.
Placement
The middle or back of the tank, singly or in a small group; it works as a soft screen in front of the back wall without blocking light like broad-leaved plants do.
Propagation
Young plants form on the flower stalk and can be separated once they have roots; a large rosette can also be divided.
