Globular Sedge is a slender, clump‑forming sedge of wet peatlands and swampy conifer forests. It grows 20–50 cm tall with very narrow, grey‑green leaves. The female flower heads are small and almost spherical, which gives the plant its name.
Did you know?
- The plant carries male and female flowers in separate little heads on the same stem.
- Its pollen is spread by the wind.
About the species
Identification
A loose, low clump of very narrow (1–2 mm), grey‑green leaves, about as long as the 20–50 cm stems. Leaf bases are reddish‑brown and often fray into fibres. The flowering stem has one short male head at the tip and 2–3 short, almost round female heads below it (each 3–7 mm), without a stalk or on a very short one, clearly spaced apart. The small leaf just below the lowest head is usually shorter than the whole head. Each seed sits in a tiny egg‑shaped, finely hairy case, making the heads look slightly fuzzy as they ripen. Differs from many sedges by its small, rounded, separate female heads. Flowers in Finland in June–July.

About the habitat
Grows on poor, wet peat: open bogs with thin peat and in swampy conifer woods; also in forest areas that are becoming waterlogged. Common across most of the country; rather scarce in Åland and in the far north‑west of Lapland.
