The Juncus effusus, commonly known as Common Rush, is a versatile native perennial grass-like plant with smooth upright stems. Blooming from late spring through summer, it features subtle, pale brown clusters of tiny flowers that emerge near the tips of the stems. Renowned for its adaptability and exceptional ability to filter runoff, this moisture-loving classic is especially beneficial for erosion control, rain garden plantings, and habitat for aquatic wildlife.
