Beach Spinifex
Spinifex sericeus

Summary

This stoloniferous, perennial grass is a primary coloniser and dominant native species of our coastal sand dunes; particularly the foredune where its long stolons can be readily observed gaining a foothold on mobile, bare sands. Leaves are densely hairy, flat to loosely inrolled and silvery in appearance.Flowers are dioecious with male and female flowers on separate plants. These appear in spring through to summer with the male flowers erect, narrow and brown whilst the female flowers produce a spherical structure which breaks free at maturity and are usually seen rolling down the beach
