Anemone patens var. multifida has frequently been recognized as a subspecies of A. patens. Although A. patens var. wolfgangiana has been used by some authors, A. patens var. multifida has priority.
Pasqueflower (as Anemone patens var. wolfgangiana) is the floral emblem of Manitoba and (as Pulsatilla hirsutissima) the state flower of South Dakota.
Native Americans used fresh leaves of Anemone patens var. multifida medicinally to treat rheumatism and neuralgia; crushed leaves for poultices; pulverized leaves to smell to alleviate headaches; and made decoctions from roots to treat lung problems (D. E. Moerman 1986).
The names Pulsatilla hirsutissima (Pursh) Britton and P. ludoviciana (Nuttall) A. Heller are illegitimate.
