Noteworthy Characteristics

Juncus tenuis, commonly called path rush, is found in the wild throughout North America. Grows to two feet tall. Path rush is found in a wide variety of weedy locations such as in parking lots, fields, thickets, woods, swamps, pastures and along roadsides and paths. Also called wire grass (even though it is a rush) because of its tough stems. Medium green leaves turn brown with frost. Insignificant, tiny flowers are clustered at or near the stem tips.

Genus name means rush.

Specific epithet means slender or thin.


No significant problems. Needs ample water. Many consider this to be a weed.


May be grown in clumps at edge of a pond or stream, among stones or pebbles, or generally as a novelty. Can also be used as a groundcover and to help control erosion.
