Black henbane is an exotic, in the USA first recorded from New York State in 1830. In the Watershed Hyoscyamus niger is usually found along roads and occasionally railroad embankments. There is an often collected population that follows roads in the Saguache Creek area west of Saguache. The Embargo Creek road photorecord (2016) would add Mineral to counties indicated in Ackerfield (2022) and BONAP (2022). Henbane is on Colorado's B list of "noxious weeds." This exotic is wide spread in all states west of the Great Plains except for California and Arizona. It has been recorded from Rio Arriba and Taos counties of New Mexico, but does not follow the Rio Grande drainage any farther south. Henbane, true to its common name, is indeed poisonous to chickens.
