Juncus hesperius, commonly known as Western Rush, is a perennial herb native to wetlands, including marshes, wet meadows, and streambanks, primarily in the Western United States. It typically grows to a height of 1-2.5 feet (0.3-0.8 meters) and a spread of 1-1.5 feet (0.3-0.5 meters). This rush features upright, cylindrical, green stems and produces small, brown, clustered flowers that bloom in the summer. The flowers are not particularly showy, but they do add a subtle texture to the plant’s overall appearance.

Western Rush is valued for its ability to thrive in wet conditions and is often used in rain gardens, bioswales, and as a naturalizing element in water features. It is also suitable for erosion control due to its dense root system. In cultivation, it prefers full sun to part shade and can tolerate a range of soil types, including clay and loam, as long as they are consistently moist or wet. It is a low-maintenance plant that requires minimal care once established.CC BY-SA 4.0
