|Carex pendula beside a stream.|

Grass-like it may be, but the stems of sedges have a triangular cross-section, easily detected if a stem is rolled between the thumb and forefinger, whereas the stems of grasses are round or oval. Sedges belong to the Papyrus family, Cyperaceae.
Gardeners who do introduce it to a pond- or stream-side may come to regret their action as the plant can become very invasive, seeding prolifically in any damp ground - as I know to my cost. Fortunately the plants are easily recognisable even when small and can be tweaked out with little effort. Druce ("Flora of Northamptonshire", 1930) curiously describes it as "septal", an obsolescent word meaning "of hedgerows"; I have never found Pendulous Sedge in, or even near, a hedgerow!
