Calamagrostis nutkaensis, commonly known as Pacific reedgrass or Nootka reedgrass, is a perennial bunchgrass that is native to coastal wetlands, meadows, and dune ecosystems along the western coast of North America, from Alaska to central California. It thrives in moist environments, often forming dense clumps in open areas where it can receive ample sunlight. Pacific reedgrass typically grows to a height of over one meter, with thick tufts of stems and several flat, grass-like leaves that can be up to a centimeter wide. The inflorescence is characteristically narrow and sparse, contributing to its subtle visual appeal. This grass is particularly adapted to environments with high humidity and salt spray, often found in coastal regions.

Pacific reedgrass is valued for its ability to stabilize soil and is used in restoration projects, especially in coastal habitats. It is also appreciated for its low maintenance requirements and is suitable for planting in naturalistic garden settings, where it can provide texture and movement. While it can tolerate a range of light conditions, from full sun to part shade, it prefers moist soils with good drainage. It is not commonly afflicted by diseases or pests, making it a resilient choice for challenging coastal environments. However, gardeners should be aware that it can spread vigorously and may require management to keep it in check.CC BY-SA 4.0
