Marram Grass, Ammophila arenaria (L.), is the single most significant plant species for the establishment and stabilisation of sand dunes. The sharp, spikey ends on the leaves can force their way upwards through the build up of dry, wind-blown sand. The rootlets and rhizomes can grow in all directions through the loose sediment – forming an inter-meshing network that binds the small particles together.
This extremely drought-resistant perennial plant grows upto 1.2 metres high. It has specially adapted leaves that can roll inwards to prevent water loss in dry conditions. The flower spikes appear between May and August; they are 25cm long and covered with smaller spikelets.
