Juncus subcaudatus, commonly known as blunt-flowered rush, is a perennial rush that is native to a variety of moist habitats across North America, including wet meadows, marshes, and the edges of streams and lakes. It typically grows up to 3 feet tall and features cylindrical, green stems with inconspicuous, brownish flowers that appear in the summer. The plant’s form is upright and grass-like, and while the flowers are not showy, they add a subtle texture to the landscape.

Blunt-flowered rush is valued for its adaptability to wet conditions and its use in wetland restoration, where it helps stabilize soil and provides habitat for wildlife. It is also used for erosion control along waterways. In cultivation, it requires consistently moist to wet soil and can tolerate standing water, making it suitable for rain gardens and the margins of ponds. It prefers full sun to partial shade and is relatively low maintenance once established. While it does not have significant disease or pest problems, it can spread aggressively in ideal conditions, which should be considered when planting.CC BY-SA 4.0
