When to see

January to December


The grey-green, rigid stems of hard rush are a distinctive feature of damp ground, such as wet grassland, riversides, dune slacks and marshes. These stems were used for basket-making and weaving in times past, but are thought to be poisonous to livestock. The brown flowers of hard rush appear from May to July.

What to look for

Hard rush has tall, rigid, grey-green stems without leaves; they are stiffer and more brittle than those of the similar Soft rush. Its brown flowers are borne in loose clusters.

Where to find

Mainly found in England and Wales, scarce elsewhere.

Did you know?

Hard rush can produce as many as 200,000 seeds per plant, which are dispersed by the wind. As with many sedges and rushes, it can spread also using rhizomes (underground stems).
