Slender Rush forms tufts of soft, bright green foliage that provide beauty and structure to the garden all year long. The leaves branch off from the base into an attractive fan-shape, with spiky flower heads positioned at the top. The flowers that appear in late summer and early fall are relatively unnoticeable but are attractive to pollinators and scores of beneficial insects.

Gardening with Slender Rush: This is a highly versatile and extraordinary low-maintenance plant when placed in the right place; such as full to mostly sunny wetlands, raingardens or wet meadows. It tolerates seasonally wet soil, provided it’s well-draining and is excellent at controlling erosion. It is also called path rush because it sends linear rhizomes that can ornamentally flank the sides of garden paths.
