Similar species (if any): Astragalus neglectus (Cooper's Milkvetch) is similar to Astragalus canadensis, but the former species is recorded from only a few counties in Wisconsin where it is listed as endangered. Astragalus neglectus has clusters with 10 to 20 flowers, whereas Astragalus canadensis has a spike of of about 12 to 30 cm long with approximately 30 to 70 flowers. Astragalus racemosus (Cream Milkvetch) also has a resemblance, but this species has not been reported from Wisconsin, Michigan, Iowa, and Illinois according to the USDA, and may only be historical in Minnesota.
Ethnobotany: No recorded uses by tribes from Wisconsin. The Blackfoot, Dakota, and Lakota used the roots as a remedy for cuts, fevers, and chest and back pains, repsectively (Moerman, p. 113, 1998). The Blackfoot also utilized the roots as a food source.
