It was named Pulsatilla chinensis for its Chinese origin. This plant is best observed on its native forest slopes in mid-spring when its delightful purple flowers, which look like small tulips, are in bloom (take care, though, as these flowers are highly toxic). A traditional use of white-haired old-man's poison was to soak its rhizome roots in water to then be used as an insecticide.
