Similar in many ways to Sisyirinchium or Libertia but with vivid gentian blue flowers through the summer. The fans of foliage are a nice fresh green.
This is not a terribly hardy species but like its relatives, it seeds about and at Pool Meadow at least (in the High Weald of East Sussex) it has persisted at least throughout the last decade. The mature plants disappeared during the harsh winter we had a while back but the seeds survived and it came back without any help from me. For a well-drained soil in sun.
