Spinifex sericeus, commonly known as hairy spinifex, rolling spinifex, beach spinifex or coastal spinifex, is a dioecious perennial grass.
It is native to Australia, New Zealand, New Caledonia, and Tonga.
It is an important pioneer species which colonises coastal dunes, binding loose sand with its horizontal runners.
Spinifex sericeus has branched stolons and rhizomes extending up to 1–2 metres (3.3–6.6 ft). The leaves have a ligule of a rim of dense hairs; the blades are flat and densely silky.
The male inflorescence is an orange-brown terminal cluster of spiky racemes subtended by silky bracts. The female inflorescence detaches at maturity, a globose seed head of sessile racemes up to 20 cm in diameter which becomes a tumbleweed.
