Juncus acuminatus, commonly known as Sharp-Fruit Rush, is a semi-deciduous perennial herb native to wetlands, including marshes, fens, and the edges of ponds and streams in North America. It typically forms dense clumps reaching up to 80 centimeters tall. The plant features an inflorescence consisting of an open array of clusters, each with up to 20 flowers. The flowers have pointed segments a few millimeters long, varying in color from light reddish-brown to greenish. The flowering season extends through the summer months, and while the flowers are not particularly showy, they add a subtle texture to the landscape.

Sharp-Fruit Rush is valued for its ability to thrive in wet conditions and is often used in rain gardens, wetland restoration projects, and as a natural water filtration system. It is also appreciated for its ease of maintenance and ability to spread, forming a natural ground cover. In cultivation, it requires full sun to part shade, consistent moisture, and prefers soils with slow drainage. While it is not prone to many diseases, it can become invasive if not managed properly in garden settings.CC BY-SA 4.0
