Calamagrostis breweri, commonly known as Brewer’s reedgrass or shorthair reedgrass, is a perennial grass native to the mountainous regions of Northern California and Oregon, specifically in subalpine and alpine zones. It typically forms dense tufts reaching up to 20 inches in height and is characterized by its lack of rhizomes and small, sparse basal leaves. The inflorescence is modest and reddish, with spikelets approximately half a centimeter long, blooming from late spring to midsummer. Brewer’s reedgrass is adapted to high-altitude ecosystems, where it contributes to the biodiversity of montane meadows and open forest clearings.

Brewer’s reedgrass is valued for its ability to thrive in challenging mountainous conditions, making it a suitable choice for restoration projects and naturalistic plantings in similar environments. It requires minimal maintenance once established and is tolerant of poor soils, though it prefers well-drained substrates. In cultivation, it is best suited to full sun or partial shade and requires moderate water. While not commonly used in ornamental horticulture, it can be utilized in rock gardens or as part of a native plant assemblage.CC BY-SA 4.0
