- NEED IN SITU PHOTOS. In the Watershed witchgrass has not been often recorded, only eight or so times. Recent iNaturalist observations (2026) show, however, that Panicum capillare is present, if uncommon. Normally this is a basin plant, annual and warm-season, often growing roadside (see iNaturalist observation #87348338, located by Hwy 160 just within the town limits of Alamosa, Alamosa Co, 2021). The inflorescence breaks at the base and becomes a tumbleweed. Perhaps because of this method of dispersal, P. capillare is a highly successful plant, and the USA distribution is ubiquitous, with the spottiest locations in the Deep South. P. capillare is present in every county of New Mexico, and follows the Rio Grande drainage down to the Big Bend region of Texas, with an isolated occurrence at the Gulf of Mexico.
