Bromus grandis
Tall brome
Family: Poaceae · Type: perennial · Native
Tall brome is a California native perennial grass found in northern Sierra Nevada Foothills, central and southern Sierra Nevada, Central West, Transverse Ranges, and Peninsular Ranges in dry, open places, shrubland, oak woodland, and conifer forest at elevations of 365 to 2,400 meters. Flowering from May to July, this grass produces hairy, spreading to nodding spikelets 25 to 35 millimeters long with delicate branching. Growing with robust stems 70 to 180 centimeters tall and 3 to 7 nodes, it develops an open, expansive structure. Its leaf blades are 18 to 38 centimeters long, 3 to 12 millimeters wide, with hairy surfaces covering both the stem and basal sheaths. The spikelets feature distinctive hairy glumes and lemmas, with awns 3 to 6 millimeters long adding texture to its elegant form.
