What is Eriophorum vaginatum

Eriophorum vaginatum, Cotton-sedge or Watasuge (scientific name: Eriophorum vaginatum) is an alpine perennial herb in the family Cyperaceae, which is native to the high mountains of the northern hemisphere.
A lot of stems come out from the rhizome and become a big plant, and many of them gather and form a community in the wetland such as Oze.
In early summer, one small pale yellow ear blooms at the end of a long, narrow flower stem.
The stringy floral capsules grow after the flowers and become spherical with white hairs (not flowers but fruit).
