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.

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).
