• Rate of growth: average
• Flowering period: May and June
• Hardiness: fully hardy
  
  

  Dramatic, indigo-violet, almost black flowers appear in May and June above strap-like grey-green leaves. This clump-forming, beardless iris, related to the moisture-loving Siberian iris, makes an eyecatching feature in a sunny, boggy area of the garden, or beside water.

• Garden care: Incorporate plenty of well-rotted garden compost or manure into the planting hole. Do not allow the plant to dry out.
