Tufted Hairgrass vs Knotted Rush

Tufted Hairgrass is a native perennial bunchgrass that forms dense clumps of dark green foliage. It produces tall, wispy seed heads in late spring and early summer, adding height and texture to the landscape. Its tidy, clump-forming habit and ornamental appeal make it well suited to smaller gardens and yards.

Tufted Hairgrass is a cool-season grass that grows most actively during the cooler parts of the growing season: spring and fall. Its adaptability allows it to establish across a range of sites, while its dense, fibrous root system helps stabilize soil. It is well suited to rangeland and prairie restoration, naturalization, erosion control, and revegetation projects.

Knotted Rush is a native perennial wetland plant found growing in marshes, swamps, wet meadows, and along shorelines. It spreads by underground rhizomes to form colonies, which can also help stabilize soils and shorelines.

Its upright, slender stems and small clusters of greenish-brown seed heads add structure to wetland plant communities. Knotted Rush is well-suited to wetland conservation, rain gardens, naturalization, and restoration projects. As a cool-season grower, it grows actively during spring and fall, when temperatures are cooler.
