Keeping the dunes alive Spinifex grass

Noongar name - Booboo

Hear all about it!

Spinifex is a perennial grass. This means that these plants live for many growing seasons. Each winter, the top portion of the plant dies back and then regrows from the same roots in the spring.

This plant is well-adapted to the extreme conditions of salt-spray, windblown sand and intense light intensity of its habitat. It grows in clumps called tussocks and it has thick creeping stems. Its leaves are flat and measure up to 300 mm long and 5-15 mm wide. Spinifex leaves are thickly covered with silvery coloured silky hairs and spinifex flowers are greenish brown.
