Iris chrysographes black-flowered

Siberian iris

• Position: full sun or partial shade
• Soil: well-drained, moderately fertile soil
• 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.
