  Glowing white flowers form in small clusters at the top of the upright stems of this elegant water iris in summer. Use it to add structural interest at the magins of a pond or stream, and team it with ground-covering or mound-forming moisture loving plants. It also works well in smaller water features on the patio.
  
  
• 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.
