Appearance
Culms are erect and 25–60 centimetres long, with grey-green leaf-blades filiform and involute, ranging from 4–30 cm long by 0.5–1 millimetre wide, i.e. bristle like. The ligules of basal leaves are 0.4–0.8 mm long and blunt, while those of culm leaves are longer, up to 2 mm, and more pointed.The roots and shoots are very closely packed together at the base of the plant producing a white, tough, highly reflective feature. The spikelets are very slender and loosely overlapping in two rows each side of the spikelet axis. Each lemma is tipped with a short awn.
Distribution
"Nardus stricta" is native to Eurasia, North Africa, and northeastern North America.Habitat
"Nardus stricta" occurs on heath, moorland, hills, and mountains on nutrient poor acidic sandy to peaty soils and is strongly calcifuge, avoiding calcareous soils. It can occur from low elevations to over 1,000 metres, becoming a community-dominant in late snow patches on mountains. "Nardus stricta" may also become a dominant species in habitats grazed by cattle or sheep because it is tough and unpalatable.It flowers from June until August. Apomixis is found to be common in this plant, with extensive colonies often proving to be a single clone.
