Did you know

  • The 'Jack' is the slender club-shaped spadix standing in the center, and the 'pulpit' is the curved striped hood (spathe) that arches over and protects him.
  • Jack-in-the-pulpit can change sex from year to year — small plants are male, larger plants become female, and stressed females revert back to male.
  • The plant lures fungus gnats by smelling like decaying mushrooms, traps them inside the pulpit, and uses them as accidental pollinators.
  • Female plants produce a stunning cluster of bright red berries in late summer, lasting long after the leaves wither.
  • All parts of the plant contain calcium oxalate crystals that cause severe burning if eaten raw, but Indigenous peoples cooked and dried the corms (called 'Indian turnip') to neutralize them.
