Distichlis distichophylla

Distichlis distichophylla, or Australian Salt-grass, is a low-growing, perennial ground cover in the family Poaceae, native to Australia. This hardy grass grows 5–20 cm tall and spreads via long, creeping rhizomes that form roots at the nodes. It is commonly found in coastal marshes and damp, salty areas, often along the fringes of saltmarshes, where it plays an important role in stabilizing soils and supporting coastal ecosystems.

The leaves of Australian Salt-grass are thin, rigid, and prickly, helping it tolerate saline and waterlogged conditions. The plant produces green to straw-coloured flowers in dense terminal spikes, approximately 2.5 cm long, on upright, leafy stems. Each spike contains up to 10 spikelets and 6–124 flowers, which are visible from October to December. Male and female flowers occur on separate plants, with fruits measuring 4–6 mm long forming in dense heads after pollination.

Distichlis distichophylla is notable for its ecological versatility and adaptability. While it is widespread and locally abundant in its natural habitats, the species’ distribution is shrinking due to habitat loss. It can also act as an indicator of rising soil salinity levels when found outside its usual coastal environments, offering valuable insights into changing land conditions.

Propagation can be somewhat challenging, as it is achieved via seed or division. However, once established, the plant's rhizomatous growth habit makes it an effective ground cover for soil stabilization and erosion control in saline environments.

With its resilience, adaptability, and ecological significance, Distichlis distichophylla is a valuable species for saltmarsh restoration, coastal revegetation, and land management projects addressing salinity. Its ability to thrive in harsh conditions while contributing to habitat structure makes it a key component of healthy coastal ecosystems.
