|discussion=<p>Occurrences of <i>Sanguisorba officinalis</i> in eastern North America represent introductions from Eurasia; the species is native in western North America. Near the southern end of its distribution in western North America, the species is generally found over serpentine substrates. There seem to be no consistent differences upon which to base a taxonomic distinction at any level between native northwestern North American plants (S. microcephala) and Eurasian <i>S. officinalis</i> in the strict sense.</p>
