Comments

Orange-peel clematis is a cultivated exotic beginning to appear in towns around the Valley (e.g., Alamosa, Monte Vista, Del Norte). The plant needs physical support. For instance the one in Del Norte is clinging to a large Ericameria nauseosa plant. It has persisted for eight seasons (2014-2022). Note that the Del Norte and Monte Vista photorecords would add Rio Grande to counties indicated in Ackerfield (2022) and BONAP (2022). For the USA distribution BONAP shows a scattering of records from 7 western USA states. So far the Rio Grande Co locations are the farthest south in the Rio Grande drainage. New Mexico has one old record (1899) that probably did not persist. Clematis orientalis is on Colorado's B list of "noxious weeds."
