Did you know

  • The species name siphilitica reflects the mistaken 18th-century belief that it could cure syphilis.
  • Native Americans, particularly the Iroquois, used root preparations to treat various conditions including coughs and fevers.
  • It is pollinated primarily by bumblebees, which are heavy enough to push open the flower's lower lip to access nectar.
  • Unlike its red cousin Lobelia cardinalis, which attracts hummingbirds, the blue species relies almost entirely on bee pollination.
  • The plant contains alkaloids similar to nicotine, including lobeline, which was once investigated as a smoking cessation aid.
