Did you know…

  • South Stack or Spathulate Fleawort smells sweetly of honey and is pollinated by bumblebees.
  • It is found on just a small region of coastline in North Wales and nowhere else in the world.
  • Recent genetic studies showed that its closest relatives are a small population of Field Fleawort in Bedfordshire but that it is distinct enough from those plants to maintain its status as a separate subspecies.

Plantlife supports a project to understand why this subspecies of Fleawort is only found in this small area of Ynys Gybi and the ecological requirements of the plants.
