Sanicula bipinnatifida is a species of flowering plant in the parsley family known by the common names purple sanicle,[1] purple black-snakeroot, and shoe buttons.

It is a perennial herb growing to a maximum height near 60 centimeters from a taproot.

The inflorescence is made up of one or more heads of bisexual and male-only flowers with tiny, curving, reddish, purple, or yellow petals.

Sanicula bipinnatifida is native to the west coast of North America from British Columbia to Baja California,[4] where it can be found in many types of habitat, including grassland, woodlands, and mountain slopes of serpentine soils.

In Canada, it is a threatened species under the Species At Risk Act, and found only in 20 extant locations on southern Vancouver Island and the surrounding Gulf Islands.
