Luzula multiflora subsp. frigida, commonly known as Common Woodrush, Frigid Woodrush, Northern Many-Flowered Woodrush, Many-Flowered Woodrush, or Northern Woodrush, is a perennial herb native to cool temperate regions of the Northern Hemisphere, including boreal forests and subarctic meadows. It is often found in moist, shaded environments such as the understory of boreal forests, along streams, and in open alpine areas. This species typically grows at a moderate rate to a height of 1-2 feet (0.3-0.6 meters) and a width of 1-1.5 feet (0.3-0.5 meters). It forms dense clumps of grass-like leaves and produces brown, inconspicuous flowers that bloom in the spring, followed by seed capsules that may persist into the fall.

Common Woodrush is valued for its ability to thrive in shaded conditions and its textural foliage, which adds visual interest to woodland gardens and naturalized areas. It is used for ground cover, erosion control, and as an accent plant in shade gardens. It is adaptable to a range of soil types, including clay, loam, and sandy soils, provided they have medium to fast drainage. While it prefers consistent moisture, it can tolerate some dryness once established. It is also relatively low-maintenance, requiring minimal care once established in the appropriate environment.CC BY-SA 4.0
