Stunning, deep purple, velvety flowers with gold streaks on the falls appear from May to June above strappy, grey-green leaves. This clump-forming, beardless iris, related to the moisture-loving Siberian iris, makes an eyecatching feature in a boggy area of the garden, or beside water.
How to care for Iris chrysographes black-flowered:
Plant in soil that has been improved with well-rotted manure or garden compost and do not allow to dry out, particularly as the plant is getting established. If grown in a container, it will need dividing and repotting every couple of years in spring. Remove the stems after flowering from the base as this will concentrate the plant's energy into producing new rhizomes. Divide and replant about every three years.
