Summary

Carex squarrosa, commonly known as Squarrose Sedge, is a semi-deciduous perennial grass native to wet meadows, marshes, and the edges of ponds and streams in the Eastern USA and Ontario. It typically grows to a height of 3 feet (0.9 meters) and a width of 1-2 feet (0.3-0.6 meters). The plant features narrow, grass-like leaves and distinctive spiky inflorescences that are greenish-brown in color, appearing in late spring to early summer. The flowers are not particularly showy, but the seed heads add texture to the garden.

Squarrose Sedge is valued for its ability to thrive in wet conditions and is often used in rain gardens, wetland restorations, and as a naturalizing element in moist garden areas. It is also suitable for erosion control along waterways. This sedge prefers consistently moist to wet soils and can tolerate occasional flooding. It is adaptable to both full sun and part shade. While generally low-maintenance, it can spread in favorable conditions and may require management to keep it in bounds.CC BY-SA 4.0
