|discussion=<p>Clematis orientalis has been reported from Idaho; it probably can be expected elsewhere.</p><!--
--><p>This species has been divided by C. Grey-Wilson (1989) into five varieties, partly correlated with their distribution in Asia. Naturalized plants in North America seem best referred to C. orientalis var. robusta Grey-Wilson, native to Afghanistan.</p><!--
--><p>Although Clematis orientalis has been naturalized in the Rocky Mountains since the late nineteenth century, it has spread especially rapidly since ca. 1975, becoming weedy and, in some localities, constituting a threat to young trees and native shrubby and herbaceous species.</p>
