Torreyochloa pallida, commonly known as Pale False Mannagrass or Weak Manna Grass, is a rhizomatous perennial grass native to North America, particularly found in wetland habitats such as marshes, fens, wet meadows, and along the edges of rivers and lakes. It is more commonly found in the northeastern United States and adjacent parts of Canada, as well as in the Pacific Northwest. This grass typically produces thick, erect to decumbent stems that can exceed 3 feet in length, and it thrives in moist, nutrient-rich soils.

Pale False Mannagrass is valued for its ability to stabilize soil and provide habitat for wildlife in wetland restoration projects. It is not typically used in ornamental gardening due to its preference for wet conditions and its relatively inconspicuous appearance. The inflorescence is a branching panicle with compressed spikelets containing up to 8 florets each, which are not particularly showy but can add texture to naturalistic plantings. In cultivation, it requires consistently moist to wet soil conditions and can tolerate partial shade, although it grows best in full sun. It is not known for any significant disease or pest issues, but its habitat requirements must be met for successful growth.CC BY-SA 4.0
