Common Cottongrass
Eriophorum angustifoliumAlso known as Common Cottonsedge, Bog Cotton, Cotton Grass
Common cottongrass transforms soggy acidic peatlands each summer into white, shimmering fields with its fluffy seed heads. Creeping underground rhizomes bind loose bog peat, helping stabilize waterlogged soil against erosion while providing crucial nesting material and forage for upland wildlife. After inconspicuous spring flowers are pollinated by wind, long silky bristles lengthen to carry seeds across vast distances on gentle breeze currents.

- Seed Observation: Watch the translucent bristles catch breezes to carry seeds long distances.
