Perennial grass with long creeping rhizomes. Stems robust, 90cm-200cm tall. Leaves bluish-green, 1.5-13 cm long. Like marram grass the leaves are inrolled leaving only the outer surface exposed to the sun and wind. Flower head is a panicle up to 25 cm long, narrow and rather lax.
Terrestrial. Short tussockland, herbfield, bare land, wetland, mainly on coastline, sand dunes.
It is expected to contribute to the degradation of sand dune habitats and is likely to invade parts of dunes where marram is less vigorous.
