Blue Sedge

Did you know invasive species are plants, animals and micro-organisms that have been introduced into areas beyond their native range and negatively impact the environment, the economy, or society? Many invasive plant species have been introduced for ornamental purposes- take Blue Sedge for example. This plant was introduced from Europe as a garden ornamental. Blue Sedge is a cool-season sedge that grows to a height of 30-45 cm, forming a dense clump that slowly creeps and spreads. Its leaves are 3 mm wide, narrow, arching, and coarse, blue green on top and blue-gray underneath.

Blue Sedge thrives in moist soils. It is often found in full sun, but also does well in the shade of large trees. It prefers areas of high pH bedrock, rich forests, swamps, and wet meadows. Blue Sedge threatens and out-competes native species that grow in these areas, including the Ram’s Head Lady’s Slipper- a legally protected species in Nova Scotia.

You can help prevent Blue Sedge and other invasive species from spreading by choosing native plants over invasive plants when planning out your garden. A great native alternative to Blue Sedge is Switchgrass. If you are removing Blue Sedge plants from your property, double bag it then leave it in the sun to rot before discarding. If you find Blue Sedge, you can report it here on iNaturalist or on our website:
