Pulsatilla patens is a species of flowering plant in the family Ranunculaceae, native to Europe, Russia, Mongolia, China, Canada and the United States. Common names include Eastern pasqueflower, prairie crocus, and cutleaf anemone.[3]


Pulsatilla patens is often placed in the genus Anemone, as Anemone patens L..[3]

Cultural associations[edit]

Pulsatilla patens is the provincial flower of Manitoba, Canada[4] and (as P. hirsutissima) is the state flower of South Dakota, United States.[5]

Declining population noted[edit]

Advocates report that the population of Pulsatilla patens is declining, due to the synergy between the prairie crocus and shortgrass prairie ecosystems. Plowing up the prairie causes the crocus to disappear.[6]

Two subspecies have been distinguished:[1][2]

  • Pulsatilla patens subsp. patens
