A creeping plant found on marshes and at pond edges, Common spike-rush is widespread and common sedge. Its bright green stems arise in tufts and are decorated with brown, egg-shaped flowers from May to July. It spreads using rhizomes (underground stems) and can form dense stands.
How to identify
Common spike-rush forms mats of bright green, upright stems. At the end of the stems, the rounded, brown spikelet (containing the flowers) appears.
Did you know?
The leaves of Common spike-rush are reduced to sheaves around the stems, so it looks as if it has none at all.
