  The combination of variegated foliage and rich purple flowers in summer, makes this a handsome addition to the edges of a pond. Plant it straight into the ground and it will spread to form a generous swathe, or pot it up if you want a more compact clump.
  
  
• Garden care: Plant out in reliably moist soil, or pot up into a pond basket and place at the margins of a pond. Cut back flowers and foliage as they fade.
