The Nordic bedstraw ( Galium boreale ) is a species of the red family (Rubiaceae).
description
The Nordic bedstraw grows as a wintering green, perennial , herbaceous plant that usually reaches heights of 15 to 50 cm. It forms a rhizome as a permanent organ, from which somewhat woody stems are often formed. It roots up to 50 centimeters deep. The bald or short-haired, square stem grows stiffly upright and is usually branched.
The leaves are four lively arranged on the stem. The simple, coarse, three-veined and dark green leaf blades are 15 to 40 mm long and 3 to 6 mm wide and have a linear-lanceolate shape and narrow towards the tip, but have no spiked tip. The leaf margin is rolled back and rough.
The Nordic bedstraw blooms mainly in the months of June to August. The dense inflorescence is pyramidal or egg-shaped and floriferous. The hermaphrodite flowers are fourfold. The white, four-lobed crown reaches a width of about 3 mm.
The mostly 2.5 mm long fruit is usually covered by curved hair.
The chromosome number of the species is 2n = 44.
Occurrence
The Nordic bedstraw occurs in the temperate and subarctic zones of the entire northern hemisphere. However, it is only widespread in parts of Central Europe .
In Germany, Galium boreale is quite common in the eastern area, while it is rare in the west and is absent over large areas.
In Austria, the Nordic bedstraw can be found frequently in all federal states.
In Switzerland, the Nordic bedstraw occurs scattered.
Galium boreale grows both in wet meadows and on semi-arid grasslands. It can also be found in sparse pine or oak forests. It prefers damp and mostly calcareous loam, clay or peat soils. It is a Molinion association character in Central Europe, but also occurs in societies of the Mesobromion or the Potentillo-Quercenion.
In the Allgäu Alps, it rises in the Tyrolean part on the southern slope of the Häselgehrberg near Häselgehr up to 1700 m above sea level.
