|discussion=<p><i>Ceanothus americanus</i> is closely related to <i>C. herbaceus</i> and <i>C. sanguineus</i>. <i>Ceanothus herbaceus</i> differs in having narrower leaf blades, short peduncles, and globose to hemispheric inflorescences. <i>Ceanothus sanguineus</i>, which occurs in western North America (except for a disjunct population in the Upper Peninsula of Michigan), differs by smooth fruit valves and inflorescences borne on stems older than the current year. Three varieties, <i></i>var.<i> americanus</i>, <i></i>var.<i> intermedius</i>, and <i></i>var.<i> pitcheri</i>, have been recognized within <i>C. americanus</i>, based on leaf shape and indumentum (M. L. Fernald 1950; H. A. Gleason and A. Cronquist 1991), but N. C. Coile (1988) provided evidence for clinal intergradation among them.</p><!--
--><p>An infusion of <i>Ceanothus americanus</i> leaves or bark was used widely by Native Americans as an anti-inflammatory and to treat gastrointestinal ailments (D. E. Moerman 1998). The dried leaves were used as a tea substitute during the American Revolution (N. L. Britton and A. Brown 1896–1898, vol. 2).</p>
