Howell’s Reedgrass

Calamagrostis howellii, commonly known as Howell’s Reedgrass, is a perennial grass native to the western United States, particularly found in wet meadows and along stream banks in the Pacific Northwest. This species typically grows to a height of 2 to 4 feet, forming dense clumps that provide excellent erosion control and habitat for various wildlife. The leaves are narrow, linear, and can reach lengths of up to 12 inches, exhibiting a vibrant green color that turns golden in the fall. The inflorescence is a feathery panicle that appears in late spring to early summer, showcasing delicate spikelets that are wind-pollinated and produce small seeds that are dispersed by air currents.

Howell’s Reedgrass plays a crucial ecological role in its native habitats, contributing to soil stabilization and providing cover for small mammals and birds. It is also valued for its ornamental qualities in landscape design, particularly in rain gardens and naturalized areas. This species has adapted to thrive in moist conditions, making it an excellent choice for wetland restoration projects. Its ability to tolerate periodic flooding and its resilience to varying soil types further enhance its utility in ecological landscaping and conservation efforts.
