Pasque (or pasqueflower) is a solitary tallgrass prairie flower that grows wild throughout South Dakota. Also called the May Day flower, prairie crocus, wind flower, Easter flower, and meadow anemone, the lovely lavender pasque is one of the first flowers to bloom in the spring, often before the winter snows have thawed. Pasque flowers were used as a medicine by Native Americans for centuries.
The pasque flower is a member of the buttercup family and is highly toxic. Some sources place the pasque flower in the genus Anemone, others the genus Pulsatilla.
