Mountain brome, Mountain Brome

Family: Poaceae · Type: perennial · Native

Mountain brome is a California native perennial grass found in open slopes, meadows, and forests across California at elevations below 3,500 meters. Flowering from May to July, this grass produces delicate, drooping spikelets 25 to 40 millimeters long with hairy green glumes. Growing 45 to 120 centimeters tall with erect to spreading stems, it forms dense tufted clumps in meadow and forest environments. Its leaves are generally hairy, with blades 6 to 12 millimeters wide that are sometimes inrolled, and feature a distinctive ligule 2 to 3.5 millimeters long. The grass produces lemmas with margins and awns 4 to 7 millimeters long, giving it a soft, textured appearance in grassland habitats.
