Juncus tenuis, commonly known as Path Rush, is a native perennial rush found in compacted soils along trails, roadsides, woodland edges, and disturbed areas throughout Illinois. It thrives in a wide range of soil types—from dry to seasonally wet—and tolerates heavy foot traffic, making it ideal for tough, worn spaces where few other natives will grow.
This low-growing, clump-forming rush typically reaches 4 to 12 inches tall. It features wiry, grass-like stems with flattened bases and produces small, inconspicuous greenish-brown flower clusters near the top of the stems from late spring through summer. The plant spreads slowly by rhizomes and can form durable groundcover in high-traffic or erosion-prone areas.
For Illinois native plant enthusiasts, Juncus tenuis is a practical and ecologically functional choice for stabilizing soil, revegetating pathways, or adding subtle greenery to lightly shaded or open habitats. While not showy, it supports biodiversity, tolerates challenging conditions, and pairs well with low-growing natives like Pennsylvania Sedge, Wild Strawberry, and Blue-Eyed Grass in resilient, low-maintenance plantings.
