Carex otrubae

A perennial of wet habitats, usually on heavy soils. It is found on the sides of streams and ponds, in ditches, swamps, wet lowland meadows and pastures, at the upper edge of saltmarshes, and, less commonly, on damp roadsides and hedge banks. In N. England and Scotland it is essentially a coastal plant. It generally grows in slightly drier conditions than C. vulpina, tending to avoid standing water. Lowland.
