Bromus tectorum plant in flower J. Morefield plant in flower

Roadsides, fields, and disturbed places, especially common along railroad tracks. First collected near Grand Rapids (Kent Co.) in 1894 and noted as “recently introduced;” now our most widespread weedy species of Bromus. A native of Europe abundantly naturalized in the United States and southern Canada. See Valliant et al. (2007). The inflorescences disarticulate at maturity, the florets then annoyingly embedding themselves in socks (and presumably animal fur).
