  3. Marram Grass


The dense, grey-green tufts of Marram Grass are a familiar feature of our coastal sand dunes: its spiky leaves featuring in many games during long summer picnics at the beach. But Marram Grass is not just a convenient child's sword or hiding place, it plays a vital role in stabilising the dunes, its fibrous, matted roots binding the sand down. Well-adapted to a harsh life at the coast, its glossy, rolled-up leaves protect it from drying out.

How to identify

The dense tufts of spiky Marram Grass are a distinctive feature of this plant. Its leaves are rolled and dense flower spikes appear in July and August.

How can people help

Marram Grass is an important feature of our coastal sand dunes: it helps to stabilise the dunes which encourages the colonisation of other plants. The Wildlife Trusts look after many coastal habitats for the benefit of all kinds of plants and wildflowers, and are working closely with farmers, landowners and developers to promote wildlife-friendly practices in these areas. We have a vision of a 'Living Landscape': a network of habitats and wildlife corridors across town and country, which are good for both wildlife and people. You can support this greener vision for the future by joining your local Wildlife Trust.
