Pulsatilla turczaninovii is a flowering plant in the family Ranunculaceae, native to Siberia, Mongolia, and northern China. The common name pasque flower refers to the spring‑blooming period of the genus Pulsatilla, which typically coincides with Easter (Passover). Derived from the Old French word pasque (“Easter”), the name is often rendered as “Easter flower”. The entire plant, including stems, leaves, and floral parts, is densely covered in silky, persistent hairs — an adaptation that provides insulation against cold temperatures and desiccation in early‑spring conditions. Fruits develop as aggregate achenes with long, feathery styles that aid wind dispersal. It is a spring ephemeroid: it emerges and flowers early in the season, often while snow patches still persist, and its above‑ground parts may senesce by midsummer. This phenology allows it to exploit a period of high light availability and reduced competition before taller vegetation develops. The species is named after Nikolai Turczaninow (1796–1864), a Russian botanist and plant collector whose work significantly advanced the knowledge of Central Asian and Siberian flora. Fresh vegetative parts of Pulsatilla are toxic due to the presence of ranunculin, a protoanemonin precursor that is released upon tissue damage and can cause irritation and gastrointestinal effects. For this reason, the plant is not used in conventional medicine, and handling or ingestion is discouraged. In some traditional contexts, Pulsatilla species have been employed in homeopathic preparations, but these applications are distinct from direct use of the fresh plant material and remain outside evidence‑based medical practice.
