Luzula comosa, commonly known as Pacific woodrush, is a perennial herb native to moist, shady coniferous and mixed forests, as well as alpine meadows in western North America, from Alaska to California and east to Colorado. It typically forms small, narrow, grasslike tufts reaching 10 to 60 centimeters in height. The plant features an erect inflorescence with clustered spikelike flowers that bloom from late spring to early summer. The flowers are composed of dark brown perianth parts that open to reveal six prominent stamens with large anthers, which are not particularly showy but have a subtle beauty.

Pacific woodrush is valued for its ability to thrive in shady, moist conditions where other plants might struggle. It is often used in woodland gardens, as ground cover, and for erosion control on slopes. This species prefers consistently moist soils and partial to full shade, making it suitable for planting under the canopy of larger trees or in naturally damp areas of the garden. While it is not known for any significant problems with diseases or pests, it can spread readily by seed and may become locally aggressive in ideal conditions.CC BY-SA 4.0
