There are two subspecies of the plant; ssp. album, Panoche pepperweed, has white flowers and ssp. jaredii, Jared's or Carrizo pepperweed, has yellow. The plant is of conservation concern, particularly ssp. album, because its range is limited and few populations are known. Much of its habitat is located on land owned and protected by the Bureau of Land Management.
