Did you know

  • The spadix generates heat through thermogenesis, warming up to 15°C above ambient temperature to volatilize scent chemicals that attract fly pollinators.
  • The bright orange-red berry clusters that appear in late summer are extremely toxic, containing oxalic acid that causes intense burning of the mouth.
  • The arrow-shaped leaves emerge in fall and persist through winter, making it one of the few plants with a reversed dormancy cycle.
  • Flies attracted by the carrion-like scent become trapped inside the spathe overnight, ensuring pollination before being released the next day.
  • Despite its toxicity when raw, the corm was historically processed into a starch called 'Portland arrowroot' and used to starch Elizabethan ruffs.
