Carex flacca Glaucous Sedge CCC DD N
This is a very common sedge particularly in swampy ground on basic soils. It droops in fruit and although its name suggests that the leaves might be glaucous, the upper surface is dull green while only the lower surface looks slightly bluey green. C. panicea (Carnation Sedge), another very common sedge, on the other hand has both leaf surfaces glaucous.
It is found throughout the British Isles and Ireland.
