That’s why small Cotton Balls decorate the Shores of the Ponds

In the wetlands of the Alps, many ponds are surrounded by pretty little white woollen balls. The protected Scheuchzer's cottongrass (Eriophorum scheuchzeri) can be seen from June to August. The plant can be found in all high mountain areas of the northern hemisphere.

The plant finds suitable habitats  above the forest boundary in flat marshes and waters silting up. It is also common in all Arctic regions from Scandinavia to Siberia, Alaska, Greenland to Iceland. The Scheuchzer's cottongrass, also known as white cottongrass, belongs to the Cyperaceae family. The plant is a perennial herb and becomes between 10 and 35 cm high. It has rolled leaf blades and its densely white woolly, spherical ears with a diameter of approximatively 2 cm are situated individually at the end of a round stem. The flowering period is from June to August. This cottongrass grows on wet, nutrient-poor peat soils, in alpine fens, ponds and silting up zones of standing waters at altitudes between 1500 and 2500 m a.s.l. The cottongrass is producing colonies via its long, red-brown rhizome, which penetrate far into the water, and thus contributing to the gradually draining of the waters and fens.
