Carex geminata (cutty grass)
Carex geminata is a species with creeping rhizomes and can form large colonies. Its green leaves can be up to 1.2m long and, as its common name suggests, have a sharp edge. It is an inhabitant of damp and swampy ground throughout much of the country. This species is not really suitable as a garden plant but could be useful in a large scale planting of wetland areas and for stream and riverbank stabilisation, as it can tolerate flooding.
