Soft Rush is a fine-textured, evergreen sedge-like grass that thrives in wet conditions and marshy areas. Its slender, columnar growth habit makes it ideal for water gardens, rain gardens, and streamside plantings.

Why grow it

Soft Rush establishes readily in consistently wet soils where many ornamental grasses struggle, making it useful for rain gardens, bioswales, and streamside restoration. Its fine texture and upright form provide visual interest in wet-site plantings without the coarseness of larger sedges or the bulk of many native wetland plants. It tolerates poor drainage and periodic inundation better than most alternatives in its ecological niche.

Watch out for

In suitable conditions, Soft Rush can spread vigorously through rhizomes and self-seeding, requiring periodic division or management to prevent overcrowding neighboring plants. It performs poorly in well-drained upland soils and full dry shade, so site selection matters considerably for success. Container-grown specimens may require consistent moisture and can decline if allowed to dry out seasonally.
