About

Carex lasiocarpa is a broadly distributed species of wetland sedge sometimes known as woollyfruit sedge or slender sedge. It is considered a species of Least Concern by the IUCN Red List due to its extensive range (much of North America, Europe, and Asia) with many stable populations.

Where it grows

Broadly distributed across much of North America and Eurasia, Carex lasiocarpa is found in a variety of freshwater wetland habitats including bogs, fens, and shorelines. It is also founds in wet areas of mountainous regions of moderate elevation. In New York state it is considered to be an indicator species for fens.
