Eriophorum angustifolium


Cotton Grass

Deep green, clump forming grass with delightful fluffy, cotton wool-like seed heads. Evergreen.


Eriophorum angustifolium produces white fluffy seed heads which from a distance look like puffs of cotton wool. Supplied bare-rooted.

Top tip: Grows equally well in water and wet soil.

Flowers: Insignificant flowers in early Spring later produce the ‘cotton wool’ seed heads.

Height of plant: 15-75cm from crown.  .

Propagation: Produces runners that can be separated and grown on.

How to plant:  Plant into a 5lt or 10lt planting basket using heavy garden loam or Westland Aquatic Soil and place on a shelf in the pond.  Fill the planting basket to a depth so that the crown of the plant is level with the rim. Hold the plant securely and fill in with soil all around the roots, pressing the soil down very firmly until the planting crate is almost filled to the brim.  For aesthetic purposes, the soil can then be top dressed with no more than 1cm of pea gravel.

Recommended planting depth:  The planting depth for this plant measured from soil surface to water surface and not including any gravel dressing is 0-15cm.
