Sporobolus virginicus

Family : Poaceae

Saltwater Couch is a hardy marine grass with underground stems. It has stiff and erect leaf blades that taper and grow to 40 cm in length. The Couch is generally a light green or brown and is often seen in clumps.

Flowers are dense spikes and have small pale branches. These appear singularly and bloom periodically throughout the year. The seed has a loose coating. This species generally has a low yield of seed per plant.

Saltwater Couch is often grazed by wallabies. It is high in protein and minerals. This grass is important for dune development and stabilising wind eroded areas. It is especially useful in poorly drained areas subject to king tides. In a garden situation, it is adaptable to various soils and is considered a good alternative to normal grass as it forms a carpet, which doesn't require mowing.
