The Snake’s Head or Fritilaria Meleagris is a species of the lily family. The flowers have a remarkable chequered pattern. In the Netherlands it’s in the wild a very rare bulb flower and therefore legally protected. The relatively large seeds spread by floating on the water surface. That explains why the plant depends on floods and high water-levels in winter for its dispersion. Not surprisingly that the last wild Snake’s Heads are found along the banks of rivers.
