|Hairy Spinifex is a strong perennial grass with long-creeping runners. The leaves are covered in a thick layer of fine hairs which slow down air movement, assisting the plant in reducing water loss from the leaves. Male flowers and female seed heads are found on separate plants.
One of the most important pioneer plants of the dunes, Hairy Spinifex can grow in bare sand and has the ability to hold and bind the sand together with its extensive root system. It grows on long, low dunes, creating a protective barrier behind which less salt-tolerant species can grow. Seed heads on female plants snap off whole, like a tumble weed.
