Species Biology


  • Flowers in April and May
  • All parts of this plant are extremely poisonous
  • First to emerge are the dark green, glossy, arrow-shaped leaves which can be spotted from January
  • The flowers are tiny.  They occur in a dense brown-purple spike (spadix) which is enclosed in a sheath (spathe). The spathe is pale green with purple margins and forms a hood at the top. 

After pollination, green berries appear on the spadix. These gradually turn to bright red
