The species is able to hybridise with the common sedge (Carex nigra) to produce a plant 20–50 centimetres (8–20 in) tall, flowering from May to June.[3] The species can be found in all of Scandinavia, ranging from common to rare, and central parts of Europe, becoming rare to the west and towards the Mediterranean, and including isolated locations in Great Britain and the Iberian Peninsula.[1][4]

The species is often found in a mosaic with other Carex, but can become almost entirely dominant. It grows in very moist soil.[5]
