Spinifex (Triodia species) is a tough, spiky tussock grass that
dominates much of the red sand desert and rocky ranges of Central Australia.

Spinifex thrives on the poorest, most arid soils Australia has to offer.
It is Spinifex that has prevented our deserts from becoming a
Sahara-like world of bare, shifting sand.

Spinifex roots go down a long way: approximately 3 metres. Generally the
roots develop from the same nodes as the shoots so that each shoot has
its own personal water supply. The spiky leaves contain a lot of silica
which makes them stiff and rigid.

Spinifex is tough and indigestible to most animals except termites.
These tiny grazers thrive on the Spinifex litter. A grass thats very
poor in nitrogen and phosphorus poses no problems for them.
