Vegetative characteristics

The millet sedge is a hibernating green, perennial herbaceous plant that reaches heights of about 10 to 50 centimeters. The above-ground parts of the plant are gray-green and bare. The gray-green leaf blades are about 2 to 6 mm wide and only later often glossy on the top, but without stomata .

Generative characteristics

The millet sedge is a variegated sedge. It has a stalked, upright male spikelet that towers above the two to three female spikelets. The upright, stalked, loose-flowered female spikelets are cylindrical with a length of 0.5 to 4 centimeters. The yellow-brown sheath of the bract is not inflated. The nerveless smooth tubes form a short, thick beak. There are three scars.

The number of chromosomes is 2n = 32.

ecology

The millet sedge is a helomorphic, mesomorphic hemicryptophyte . It also reproduces vegetatively with the help of its rhizome or from underground runners .

The flowering period extends from May to July. The pollination is carried by the wind ( anemophily ). The diaspores spread through the wind ( anemochory ) and through Velcro spreading and self-spreading. The seeds are cold germinating.

Occurrence

The millet sedge is common from Europe to Central Asia. It is also found in Morocco and Greenland. In eastern North America it occurs as a neophyte .

It is common in Central Europe , but is absent there in smaller areas, especially in the lowlands and in landscapes with little precipitation; it is usually not found in abundance at its place of discovery. It is widespread throughout Germany except in the central German arid regions. It rises in the Alps to the tree line. In the Allgäu Alps, it rises in Bavaria in the moor on the Windecksattel north of the Hohen Ifen up to 1750 m above sea level.

In Central Europe it populates flat moors, swamp meadows and ditches, it also goes on light forest paths. The moderately nutrient-demanding millet-sedge thrives in Germany on partly flooded river edges, low and spring moors and on damp, poor grassland. It thrives in societies of the orders Tofieldietalia, Caricetalia fuscae or Molinietalia.

The millet sedge thrives best on at least moderately base-rich, often somewhat acidic and at least damp or even wet soils that can be peaty, muddy or loamy. She can just barely endure weak nitrogen fertilization.
