Carex vesicaria
Also called Bladder Sedge, Inflated Sedge, Lesser Bladder Sedge, Small Inflated Sedge, Tufted Lake Sedge
Carex vesicaria is an essentially Holarctic species of sedge known as bladder sedge, inflated sedge, and blister sedge. It has been used to insulate footwear in Norway, Sweden and among the Sami people, and for basketry in North America.
Bladder sedge has a circumpolar, boreo-temperate distribution. It is native to northern North America being recorded over most of Canada and the northern United States, as far south as California. It can also be found in nearly all of northern Europe and northern Asia as far as Japan and Korea. It is widespread in Britain and Ireland although it is absent from the Orkney and Shetland and very rare in the Western Isles.
Carex vesicaria was cultivated in North America by indigenous people as its rhizomes were used for basketry, The dried fibres, were sometimes used as thermal insulation in footwear in polar regions, are known as sennegrass, saennegrass or similar, from the plant's Bokmål name sennegras.
