The quivering grass sedge ( Carex brizoides ), also alpine grass , sea ​​grass sedge , forest hair or Rasch belongs to the genus of sedges ( Carex ) and is a common sour grass family (Cyperaceae) in southern and southwestern Germany . The common name Sacher is also used for the Carinthia region .

description

The quaking grass sedge is a medium-high sedge with a height of 30 to 70 cm and a whitish-green to yellow-brownish color. Often it is stand-forming and grows in extensive, dense lawns. In this state the stocks look like a surging lake, from which the plant got its name. It has long, slack, bent to almost lying leaves and stems . The stem is sharp triangular.

The flowering period lasts from May to June. The inflorescences are loose, the husks are initially reddish brown and shiny white skinned, but later straw yellow and dull. The pale yellow spikelets are six to eight, are usually curved downwards or outwards, narrowly lanceolate and 8 to 10 mm long.

The number of chromosomes is 2n = 58.

Occurrence and locations

The distribution area of ​​the quaking grass sedge extends from central and southern Europe to the Ukraine and north-western Turkey.

The quaking grass sedge is widespread in Central Europe and occurs in coniferous forests, bushes, borders, fields, fresh and wet meadows near forests and their fallow, but also in mixed deciduous forests. It grows on stagnant to seep-damp, base- and nutrient-poor, moderately acidic, humus-rich sandy and loamy soils with sometimes high-standing or compacted soil water. It is a wetting and compaction indicator. It thrives in companies of the Alno-Ulmion, Carpinion, Fagion or Calthion associations. In the Allgäu Alps, it rises just a little over 1000 meters above sea level.

use

It used to be so heavily used as upholstery material that in individual forests in the Rhine Valley the income from this secondary use exceeded the income from wood production. It was obtained by plucking (in Upper Austria by mowing) and dried in sunny places. It was used to twist ropes with simple machines and put it on the market in this form. This so-called seaweed spinning causes the material to curl and is clearly superior to the straw previously used for filling mattresses. Seaweed was especially fashionable during the world wars, when fiber material was scarce and the need for camp beds was high. Seaweed spinning experienced a final high point during the Korean War , before it was replaced by plastics. The alpine grass was also used in smaller quantities for braiding, such as carrying straps, shoes, mats, etc. For this, however, it must not be spun, but should remain smooth.
